[AAP-78702] Add CleanTextMixin to serializers

[daphnemaeve]

Description

Jira ticket: https://redhat.atlassian.net/browse/AAP-78702

Adds CleanTextMixin from django-ansible-base to EDA API serializers that handle create and update operations. This implements two-tier text field validation:

• Tier 1 (name fields): strict character allowlist — only letters, numbers, spaces, hyphens, underscores, dots, and @
• Tier 2 (other text fields): dangerous pattern blocklist — rejects HTML tags, JavaScript protocols, event handlers, shell substitution, backticks, null bytes, and ANSI escapes

Why is this change needed?

EDA endpoints currently accept unsanitized text input in resource names and free-text fields, creating potential XSS and injection vulnerabilities.

How does this change address the issue?

By adding CleanTextMixin as the first mixin in the inheritance chain for each serializer, validation automatically runs as part of serializer.validate(). Each overridden validate() now chains to super().validate(...) so the mixin's checks actually execute. The mixin:

• Auto-discovers text fields (CharField, TextField) from the model
• Applies the appropriate validation tier based on field name
• Grandfathers existing invalid data (unchanged values on update pass validation)
• Is gated behind the ENHANCED_INPUT_VALIDATION_ENABLED install-time setting (gating logic lives in DAB within CleanTextMixin; EDA does not enable it by default in this PR)

Changes

Added CleanTextMixin to the write-path serializers across:

• Activations: ActivationSerializer, ActivationCreateSerializer, ActivationCopySerializer, ActivationUpdateSerializer
• Credentials: EdaCredentialSerializer, EdaCredentialCopySerializer, EdaCredentialCreateSerializer, EdaCredentialUpdateSerializer, CredentialInputSourceSerializer, CredentialInputSourceCreateSerializer, CredentialInputSourceUpdateSerializer, CredentialTypeSerializer, CredentialTypeCreateSerializer, AwxTokenCreateSerializer
• Decision environments: DecisionEnvironmentSerializer, DecisionEnvironmentCreateSerializer
• Event streams: EventStreamInSerializer, EventStreamOutSerializer
• Projects: ProjectSerializer, ProjectCreateRequestSerializer, ProjectUpdateRequestSerializer
• Organizations, teams, users: OrganizationSerializer, OrganizationCreateSerializer, TeamSerializer, TeamCreateSerializer, TeamUpdateSerializer, UserSerializer, UserUpdateSerializerBase

Fields that legitimately contain non-plain-text content are excluded via excluded_fields so they aren't rejected as unsafe:

• extra_var (activation) — Jinja2 template syntax from credential injectors
• injectors (credential type) — Jinja2 template syntax
• inputs (eda credential) and metadata (credential input source) — arbitrary credential payloads
• token (AWX token) — secret token value

Validation Behavior

• Tier 1 (name fields): strict character allowlist (alphanumeric, hyphen, underscore, space, period, @)
• Tier 2 (other text): dangerous pattern blocklist (HTML tags, JS protocol, event handlers, shell syntax)
• Grandfathering: unchanged invalid values on update pass validation (backward compatible)
• Install-time setting: gated behind ENHANCED_INPUT_VALIDATION_ENABLED, disabled by default until enabled at the deployment/manifest level

Does this change introduce any new dependencies, blockers or breaking changes?

Adds nh3 and regex.

No behavior change for existing deployments until ENHANCED_INPUT_VALIDATION_ENABLED is turned on. Once enabled, new/changed values with unsafe names or content will be rejected on create/update.

How can it be tested?

Manual testing

Prerequisites
• aap-dev environment set up and functional
• Access to the EDA UI

1. Environment Setup

2. Configure your aap-dev sources to point at:
      - DAB → devel branch
      - EDA Server → PR branch (refs/pull/1660/head or the author's feature branch)

3. Start the environment and ensure the EDA UI is accessible.

4. Enable the feature gate — set this in your environment:ENHANCED_INPUT_VALIDATION_ENABLED=True
   (The validation is a no-op when this is False, so you must enable it.)

5. Test Inputs

Use these values throughout:

INVALID name: <script>alert(1)</script>
INVALID description: $(rm -rf /)
VALID name: My Test Resource
VALID description: A perfectly normal description

Tier 1 rejects HTML/XSS-style patterns in name fields. Tier 2 rejects shell injection patterns in description and other free-text fields.

Test cases

For each resource below, test via the EDA UI. Every create and update action should now validate name and description fields.

3a. Organizations

• Create → Enter <script>alert(1)</script> as the name → expect validation error
• Create → Enter My Test Org as name, $(rm -rf /) as description → expect validation error
• Create → Enter My Test Org as name, A normal description → expect success

3b. Teams

• Create → Enter <script>alert(1)</script> as the name → expect validation error
• Create → Enter Valid Team Name, $(rm -rf /) as description → expect validation error
• Create → Enter Valid Team Name, Normal description → expect success

3c. Projects

• Create → Enter <script>alert(1)</script> as the project name → expect validation error
• Create → Enter a valid name, $(rm -rf /) as description → expect validation error
• Create → Enter a valid name and description with a valid SCM URL → expect success

3d. Decision Environments

• Create → Enter <script>alert(1)</script> as the name → expect validation error
• Create → Enter a valid name with a valid image URL → expect success

3e. Credentials

• Create → Enter <script>alert(1)</script> as the credential name → expect validation error
• Create → Enter $(rm -rf /) as the description → expect validation error
• Create → Enter a valid name and description → expect success

3f. Activations

• Create → Enter <script>alert(1)</script> as the activation name → expect validation error
• Create → Enter $(rm -rf /) as the description → expect validation error
• Create → Enter a valid name and description → expect success

3g. Users

• Create → Enter <script>alert(1)</script> as the username → expect validation error
• Create → Enter a valid username (e.g. valid.user123) → expect success

Automated tests

• tests/integration/api/test_clean_text_mixin.py covers valid text, rejected unsafe content, and update/grandfathering behavior across all updated serializers with ENHANCED_INPUT_VALIDATION_ENABLED=True.
• ATF tests: https://gitlab.cee.redhat.com/ansible/testing/eda-test-suite/-/merge_requests/142

Summary by CodeRabbit

Bug Fixes

• Improved text validation for activations, credentials, projects, teams, users, organizations, event streams, and decision environments.
• Unsafe or invalid text is rejected while structured metadata, credential inputs, tokens, and other supported fields remain unaffected.
• Activation copies now validate descriptions, service names, and source mappings before duplication.
• Updates continue to support unchanged, pre-existing values that do not meet newer validation rules.

Tests

• Added integration coverage for valid and rejected text, excluded fields, copy validation, and update handling.

Code Review: [AAP-78702] Add CleanTextMixin to EDA serializers (github.com/#1660)

Verdict: NEEDS_CHANGES

Scores

Lens	Score	Findings
Functionality	10/10	0 scored (1 Nit, 0 pts)
Security	10/10	0 new scored (1 unresolved known blocker, not re-scored)
Quality	7.5/10	2 Major, 1 Minor
Overall	9.2/10

Verdict is NEEDS_CHANGES because of (a) two Major Quality findings below and (b) an unresolved Major-severity known blocker (CodeRabbit, still present) — see Known Blockers section.

---

Known Blockers (from existing PR discussion — verified, not duplicated as new findings)

1. src/aap_eda/api/serializers/activation.py:721-791 — @coderabbitai (Major): "When enhanced input validation is enabled, ActivationCopySerializer validates only name. copy() then adds activation.description and passes it to super().create(copied_data), so description bypasses CleanTextMixin and can persist blocklisted text."

   Status: CONFIRMED, still unresolved at HEAD (a5d80d7). Independently verified by both review agents and the coordinator:

   • ActivationCopySerializer.Meta.fields = ["name"] — the only field DRF/CleanTextMixin ever sees via is_valid().
   • copy() builds copied_data including "description": activation.description plus ~20 other fields, then calls return super().create(copied_data) directly (serializers.ModelSerializer.create()), which never invokes validate().
   • View confirms the chain: serializer.is_valid(raise_exception=True) (validates only name) → serializer.copy() (persists everything else unvalidated) — src/aap_eda/api/views/activation.py:650-655.
   • No test coverage: tests/integration/api/test_clean_text_mixin.py has a TestActivationCleanText class but no test exercises the /copy/ action (grep -i copy on the file matches only license-header text).
   • Sibling check (ruled out): EdaCredentialCopySerializer does not have this problem — its copy() view action routes through EdaCredentialCreateSerializer(data=post_data).is_valid(), so full CleanTextMixin validation runs on the copied description. EdaCredentialCopySerializer itself is only ever referenced in @extend_schema(request=...) for docs, never instantiated in view logic.
   • Pattern propagation: searched the entire diff and all copy/clone/duplicate actions repo-wide — Activation and EdaCredential are the only two copy paths in the codebase; no other instance of this bug class exists.

2. Two false leads checked and ruled out (not real gaps, included here for transparency, not scored):

   • UserUpdateIsSuperuserSerializer (user.py:161-173) overrides validate() without calling super(), silently skipping CleanTextMixin — but Meta.fields = ["is_superuser"] is a BooleanField only, so there's no text field to protect. Immaterial, and pre-existing (unrelated to this diff).
   • Project.proxy (EncryptedTextField) is not in ProjectCreateRequestSerializer/ProjectUpdateRequestSerializer's excluded_fields, unlike the analogous inputs/metadata/token fields elsewhere. Considered as a possible gap, but refuted: proxy isn't name-pattern-matched into Tier 1, so at worst a legitimate proxy URL with a blocklisted character gets a loud 400 rejection — a usability nit, not an injection/bypass risk. No exploitable attack surface; not scored.

Findings

Critical

(none)

Major

1. [Quality] src/aap_eda/api/serializers/activation.py:721-791 ActivationCopySerializer.Meta.fields = ["name"] declares a one-field write contract, but copy() persists ~20 additional fields (including description) via a hand-built dict passed straight to super().create(). This is a leaky abstraction distinct from the security angle above: a maintainer reading Meta.fields would reasonably assume that's the entire validated/writable surface of the serializer, which is false.

   • Evidence: class Meta:\n model = models.Activation\n fields = ["name"] … copied_data = {"name": self.validated_data["name"], "description": activation.description, ...} … return super().create(copied_data)
   • Confidence: HIGH
   • Fix: Route copy() through a serializer whose Meta.fields reflects everything actually persisted (so is_valid() covers all of it and picks up CleanTextMixin), or at minimum validate description explicitly before calling create().
   • Points: 1

2. [Quality] tests/integration/api/test_clean_text_mixin.py — no test asserts that content in any excluded_fields entry (extra_var, injectors, inputs, metadata, token) is actually accepted once ENHANCED_INPUT_VALIDATION_ENABLED=True. The 762-line suite thoroughly tests that name/description get rejected/accepted, but never exercises the exemption path itself. A future typo in an excluded_fields value, or an upstream DAB change to auto-discovery, would silently start rejecting legitimate Jinja2/encrypted-secret content with no test catching it — a silent-failure risk one level above a loud one.

   • Evidence: no reference to extra_var, injectors, or token anywhere in the test file; no assertion of HTTP_201_CREATED/is_valid()==True for a payload containing Jinja2 template syntax or shell-metacharacter-bearing secret values.
   • Confidence: HIGH
   • Fix: Add e.g. test_extra_var_jinja2_content_accepted (Activation, posting extra_var containing {{ template }} and asserting 201), test_injectors_jinja2_content_accepted (CredentialType), and test_token_value_not_validated (AwxToken, with a token value that would otherwise trip the Tier-2 blocklist).
   • Points: 1

Minor

3. [Quality] CleanTextMixin was added to four serializers confirmed never used to process a write (no data= instantiation anywhere in src/ or tests/), undercutting the PR's stated "write-path serializers" framing:

   • ActivationSerializer (activation.py:370) — entirely unused for input anywhere in the codebase.
   • EventStreamOutSerializer (event_stream.py:99) — only ever instantiated with instance/many=True for response bodies.
   • EdaCredentialCopySerializer (eda_credential.py:128) — only referenced via @extend_schema(request=...); the real copy flow uses EdaCredentialCreateSerializer.
   • OrganizationCreateSerializer (organization.py:71) — get_serializer_class() always returns OrganizationSerializer, even for create; OrganizationCreateSerializer is never wired in despite its name.

   Cross-checked every real write path in the 8 affected domains against get_serializer_class/data= usage — confirmed no actual write-path serializer was missed by the PR; this is dead weight plus a process signal, not a coverage gap.

   • Evidence: see grep results in Verification Results below.
   • Confidence: HIGH
   • Fix: Remove CleanTextMixin from these four classes (no behavioral effect today), or add a one-line comment noting they're response/schema-only.
   • Points: 0.5

Nit

4. [Functionality] organization.py, team.py vs. user.py — inconsistent ordering of self.validate_shared_resource() relative to super().validate(data) across the touched validate() overrides (some call the shared-resource check before the mixin, UserUpdateSerializerBase after). Both orders produce a correct 4xx; only which error a client sees first differs when both would fail. No functional impact.
   • Evidence: self.validate_shared_resource()\n return super().validate(data) (organization.py) vs. data = super().validate(data)\n self.validate_shared_resource()\n return data (user.py)
   • Confidence: HIGH
   • Fix: Not required — purely stylistic.
   • Points: 0

---

MRO / super() Chain Verification (Functionality lens — full trace, all 10 files)

Every one of the ~28 touched serializer classes was traced individually. CleanTextMixin is listed first (or otherwise MRO-safe) in every touched base-class tuple, and every overridden validate() in a class carrying the mixin correctly calls and returns super().validate(data) on every return path, including the two-branch case in EdaCredentialUpdateSerializer.validate(). No broken chains found.

excluded_fields Accuracy Check (Functionality lens)

Serializer(s)	excluded_fields	Verified against model	Result
Activation family	{"extra_var"}	Activation.extra_var = TextField	Correct
CredentialType family	{"injectors"}	CredentialType.injectors = JSONField	Correct (defensive/redundant — not a TextField subtype anyway)
EdaCredential family	{"inputs"}	EdaCredential.inputs = EncryptedTextField(TextField subclass), exposed as serializers.JSONField()	Correct and necessary — without it, dict values would be validated as free text
CredentialInputSource family	{"metadata"}	same EncryptedTextField pattern	Correct and necessary
AwxTokenCreateSerializer	{"token"}	AwxToken.token = EncryptedTextField, real string field	Correct and necessary

No typos found in any excluded_fields entry.

Needs Human Judgment

• Jira AAP-78702 could not be fetched (auth-gated redhat.atlassian.net, no credentials available in this session) — acceptance criteria/DoD not cross-checked against the implementation. Only the PR description was used for change intent.
• CI/pipeline status could not be checked — both GitHub auth paths (SSH and the gh token wrapper) were unavailable in this session. CI state on PR [AAP-78702] Add CleanTextMixin to serializers #1660 is unknown to this review.
• Other unresolved PR discussions — only the single CodeRabbit comment pointed out by the requester was checked. Any other open review threads on PR [AAP-78702] Add CleanTextMixin to serializers #1660 are not accounted for in this review.
• Backward-compatibility of ENHANCED_INPUT_VALIDATION_ENABLED: turning the flag on rejects new/changed values that were previously accepted. Grandfathering covers unchanged values on update, but there's no migration/audit tooling in this PR to help an operator find existing data that would newly fail validation. Legitimate rollout question, not a diff defect.

Incidental Findings (out of scope — not scored)

• UserUpdateIsSuperuserSerializer.validate() skips super() entirely — pre-existing, unrelated to this diff, immaterial (no text field in scope).
• django-ansible-base is pinned to a floating branch = "devel" in pyproject.toml (anchored only via poetry.lock's resolved commit) — pre-existing dependency-pinning strategy, unchanged by this diff.
• EdaCredentialTestSerializer (dry-run "test credential" action) isn't wrapped in CleanTextMixin and wasn't touched by this PR — doesn't persist data, so no persistence-of-unsafe-text risk today, but worth a follow-up if that view's semantics ever change.
• EventStreamViewSet.partial_update manually copies validated_data onto the instance and calls .save() directly rather than serializer.save() — unusual but not a bypass, since is_valid() already ran.

Limitations

This review was performed by an AI agent (two-lens: Security, and Functionality+Quality run in parallel) in local mode without GitHub API/SSH access (both auth paths were unavailable this session). It does not understand business context, domain intent, organizational constraints, or deployment/rollout environment specifics. LOW-confidence findings and items in "Needs Human Judgment" require human verification. The django-ansible-base package (source of CleanTextMixin) is not installed in this sandbox, so its exact validation/auto-discovery behavior was inferred from the PR description and the new test file's black-box assertions, not read directly. This review is a first pass, not a final approval.

Path to 10/10

1. [Quality/Security] activation.py:721-791 (+1 pt, resolves known blocker too)

   In ActivationCopySerializer.copy(), description and ~20 other fields are written via super().create(copied_data) without ever passing through validate(). Change copy() to validate the full copied_data payload (e.g., build it through a serializer whose Meta.fields includes description, or explicitly call the description through CleanTextMixin's validation logic) before calling create().

2. [Quality] tests/integration/api/test_clean_text_mixin.py (+1 pt)

   Add regression tests proving each excluded_fields entry is actually exempted: extra_var (Activation) and injectors (CredentialType) accept Jinja2 template syntax; token (AwxToken) accepts a value containing Tier-2-blocklisted characters (e.g. $(...)) — all with ENHANCED_INPUT_VALIDATION_ENABLED=True.

3. [Quality] activation.py:370, event_stream.py:99, eda_credential.py:128, organization.py:71 (+0.5 pt)

   Remove CleanTextMixin from ActivationSerializer, EventStreamOutSerializer, EdaCredentialCopySerializer, and OrganizationCreateSerializer — none are ever instantiated with data=, so the mixin has no effect there. If kept intentionally, add a one-line comment saying so.

Final Score

Overall: 9.2/10 — NEEDS_CHANGES

Tip

For best results, initiate chat on the files or code changes.

@vidyanambiar, thanks for the detailed review.

The ActivationCopySerializer.copy() path is the priority issue. It persists description and other copied fields without validation through the serializer write contract.

The missing excluded_fields acceptance tests are also valid regression coverage gaps. Tests should confirm that exempted template and secret content remains accepted when enhanced validation is enabled.

The four response- or schema-only serializers do not require CleanTextMixin for current write behavior. Removing the mixin or documenting the intentional use would improve clarity.

Code Review: [AAP-78702] Add CleanTextMixin to serializers

Verdict: NEEDS_CHANGES
Score: 8.2/10 (Functionality 8, Security 8, Quality 8.5)
Risk: CRITICAL (security-sensitive credential/user serializers touched, broad API surface — 10 of 11 changed files are serializers; no breaking changes detected)

Key Findings

Critical

• activation.py:749-817 — ActivationCopySerializer.copy()'s fix re-validates the copied description but not k8s_service_name/source_mappings, which are copied from the source activation into copied_data and persisted via super().create() with zero validation. Same silent-bypass bug class the PR exists to close, just on two sibling fields.

Major

• [Security] project.py — Project.proxy (embedded proxy credentials, EncryptedTextField) isn't in excluded_fields on either Project create/update serializer, unlike every other secret field this PR handles (inputs, metadata, token). Legitimate high-entropy proxy passwords will be blocklist-rejected once ENHANCED_INPUT_VALIDATION_ENABLED=True.
• [Security] user.py — User.password is similarly not excluded on UserUpdateSerializerBase, inconsistent with how AwxToken.token is already handled.
• [Quality] 8 serializers (ActivationSerializer, ProjectSerializer, CredentialTypeSerializer, DecisionEnvironmentSerializer, TeamSerializer, UserSerializer, OrganizationCreateSerializer, EdaCredentialCopySerializer) carry a non-functional CleanTextMixin — confirmed via grep none are ever instantiated with data=. A prior review pass fixed a different, non-overlapping set of read-only serializers.

Resolved since a prior review pass: excluded_fields acceptance tests now exist (TestExcludedFieldsCleanText), and validate_shared_resource() ordering is now consistent across organization/team/user.

Path to 10/10

1. Extend _ActivationCopyTextCheckSerializer.Meta.fields to also cover k8s_service_name and source_mappings, and use the re-validated values in copied_data. (+2)
2. Add excluded_fields = frozenset({"proxy"}) to ProjectCreateRequestSerializer/ProjectUpdateRequestSerializer. (+1)
3. Add excluded_fields = frozenset({"password"}) to UserUpdateSerializerBase. (+1)

Full findings with evidence, verification commands, and confidence levels: available on request.

Excluded Fields & Security Review

Focused review analyzing excluded fields, ensuring no fields are missed, and checking for security gaps.

1. Excluded Fields Audit — All 7 Categories Justified ✅

Every excluded_fields declaration has a sound technical rationale:

Category	Write Serializer(s)	excluded_fields	Rationale
extra_var	ActivationCreateSerializer, ActivationUpdateSerializer	{"extra_var"}	Jinja2 template syntax ({{ }}) — false-positive risk
injectors	CredentialTypeCreateSerializer	{"injectors"}	Jinja2 templated JSON for credential injection
inputs	EdaCredentialCreateSerializer, EdaCredentialUpdateSerializer	{"inputs"}	Secret credential values (EncryptedTextField)
metadata	CredentialInputSourceCreateSerializer, CredentialInputSourceUpdateSerializer	{"metadata"}	Programmatic credential metadata (EncryptedTextField)
token	AwxTokenCreateSerializer	{"token"}	Secret AWX API token (EncryptedTextField)
password	UserUpdateSerializerBase	{"password"}	Password field
proxy	ProjectCreateRequestSerializer, ProjectUpdateRequestSerializer	{"proxy"}	Proxy URL with possible embedded credentials

2. Missing Fields — None Found ✅

All write-path serializers were checked. No field that should be excluded is missing from excluded_fields. The exclusion boundary correctly covers three categories: Jinja2 template fields, encrypted/secret fields, and password fields. All other free-text fields (name, description, k8s_service_name, source_mappings, etc.) are correctly validated by the mixin.

3. Security Gap Analysis

3a. Copy-path bypass — Resolved ✅

ActivationCopySerializer.copy() uses _ActivationCopyTextCheckSerializer to re-validate description, k8s_service_name, and source_mappings as new content during copy. This is a solid defense-in-depth approach — even though source data was presumably validated on original creation, re-validating prevents stale pre-mixin data from propagating unchecked.

EdaCredentialCopySerializer's copy flow is also safe — the view routes copied data through EdaCredentialCreateSerializer(data=post_data).is_valid().

3b. validate() chain integrity — Sound ✅

Every serializer that overrides validate() correctly chains to return super().validate(data), ensuring CleanTextMixin.validate() is always invoked.

3c. MRO ordering — Correct ✅

CleanTextMixin is consistently first in the inheritance list, ensuring its validate() runs before the base class.

3d. Feature gate — Acceptable ✅

Validation is gated behind ENHANCED_INPUT_VALIDATION_ENABLED. When disabled, the mixin is a no-op. Appropriate for staged rollout.

4. Test Coverage — 7/7 Excluded Field Categories Covered ✅

TestExcludedFieldsCleanText has regression tests for every exclusion category:

• test_activation_extra_var_excluded — extra_var ✅
• test_credential_type_injectors_excluded — injectors ✅
• test_eda_credential_inputs_excluded — inputs ✅
• test_awx_token_excluded — token ✅
• test_credential_input_source_metadata_excluded — metadata ✅
• test_project_proxy_excluded — proxy ✅
• test_user_password_excluded — password ✅

5. CleanTextMixin Scope

CleanTextMixin is applied only to write-path serializers that process user input. Read-only serializers (used only for GET responses) do not carry the mixin, keeping the codebase clean.

Summary

Area	Status
Excluded fields correctness	✅ All 7 categories justified
Missing field coverage	✅ No write-path fields missed
Copy-path bypass	✅ Resolved via helper serializer
validate() chain	✅ All chains intact
MRO ordering	✅ Consistent
Test coverage for exclusions	✅ 7/7 covered
Mixin scope	✅ Write-path only

No security gaps identified. From an excluded-fields and security perspective, this PR is ready to merge.

Review summary

I reviewed the current head (1ee6ad6). I found no blocking correctness or security issue. The PR is mergeable and the current checks are green.

Non-blocking follow-up

The activation copy helper now revalidates description, k8s_service_name, and source_mappings, and uses the validated values before persistence. The copy-specific integration tests cover description propagation and grandfathered descriptions, but do not independently exercise rejection of unsafe k8s_service_name or source_mappings values. Please consider adding one negative test for each field so a future regression in this manually validated path is caught.

Scope/documentation

The description says there are no new dependencies or blockers, but the diff also updates the locked django-ansible-base version, adds nh3/regex lock entries, and changes the pinned Tekton ATF test bundle digest. These may be intentional, but please document them in the PR description or split unrelated changes.

With those non-blocking cleanup items noted, the serializer validation wiring and excluded-field coverage look sound.
