From 6de06d5b411c4121b8da1f3b7a73e648d9425439 Mon Sep 17 00:00:00 2001 From: vivekchand Date: Tue, 8 Sep 2026 10:06:23 +0200 Subject: [PATCH 01/32] =?UTF-8?q?feat:=20build=20your=20own=20UI=20?= =?UTF-8?q?=E2=80=94=20a=20keyed,=20scoped=20read=20API=20over=20the=20q/1?= =?UTF-8?q?=20contract?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ClawMetry ships one dashboard, and a user who wanted a different view of their own data had to fork it. Every number the dashboard draws already comes from a declared, versioned read contract (q/1); the only thing allowed to call it was the dashboard itself, because the only gate in front of it was the browser's same-origin rule. This adds the door: clawmetry key create --name my-ui --scope read:metrics \ --origin http://localhost:3000 GET /api/q/1/ one declared query GET /api/q/1 what this key can read GET /api/q/1/llms.txt the API, written for a coding agent Four pieces, all built on what existed: * Read scopes live ON the contract. Every q/1 method declares one of read:metrics / read:sessions / read:traces / read:content next to its trust class, so a new method cannot drift out of the scope model and docs/QUERY_CONTRACT.md regenerates with a scope table. * clawmetry/apikeys.py + `clawmetry key` + a Security-tab panel. SHA-256 in ~/.clawmetry/api_keys.json (0600), scopes plus an origin allowlist. * routes/public_api.py dispatches through the SAME local_query._dispatch the dashboard uses, so there is no second query surface. * examples/custom-ui/ (one file, no build step) and docs/BUILD_YOUR_OWN_UI.md. The security decision this turns on: adding CORS to a service on localhost is how local tools get robbed. Any page in any tab can already SEND a request to 127.0.0.1:8900; the only reason that is harmless is that the browser will not let it READ the reply. So loopback earns nothing here (a key is always required, which inverts the rest of the dashboard), there is no wildcard origin at all, key management stays on the ordinary dashboard blueprint behind the same-origin write guard, and the API is GET only. Nothing here writes: this adds no entry to the control plane. read:metrics is exactly the plaintext trust class, pinned by a test. That equality is what makes "a browser-resident key cannot return a prompt" a promise rather than a hope. Verified: the starter served from localhost:3000 rendered $750 of real 30-day cost across 10 runtimes from a ClawMetry on another port, and on that same page a valid full-scope key bound to a different origin was refused by the browser. 48 guards in tests/test_public_api_keys.py (registered in ci.yml), three mutations proven red.

Every number the dashboard draws already comes from a declared, versioned read contract (`q/1`, 17 live methods, per-method arg schemas, additive-only, drift-tested). The only thing allowed to call it was the dashboard itself, because the only gate in front of it was the browser's same-origin rule: there was no API key anywhere, and no `Access-Control-Allow-Origin` header anywhere in the codebase. So the options were fork the dashboard, scrape the HTML, or do without. Meanwhile the generation tools got good enough that a purpose-built view is an afternoon of work *if* the data has an addressable API. Ours did not have a door. +- **What:** four pieces, all built on what already existed. (1) **Read scopes live on the contract**: every `q/1` method now declares one of `read:metrics`, `read:sessions`, `read:traces`, `read:content`, in `clawmetry/query_contract.py` next to its trust class, so a new method cannot drift out of the scope model and `docs/QUERY_CONTRACT.md` regenerates with a scope table. (2) **Scoped keys** (`clawmetry/apikeys.py`, `clawmetry key create|list|revoke|scopes`, and a panel on the Security tab): SHA-256 in `~/.clawmetry/api_keys.json` at 0600, each key carrying scopes and a browser-origin allowlist. (3) **`GET /api/q/1/`** (`routes/public_api.py`), dispatching through the *same* `routes.local_query._dispatch` the dashboard uses, so there is no second query surface to keep correct. (4) **`GET /api/q/1/llms.txt`**, the whole API written for a coding agent to read in one pass, generated from the contract and scoped to the presented key. Plus a starter (`examples/custom-ui/`, one file, no build step) and a walkthrough (`docs/BUILD_YOUR_OWN_UI.md`). +- **The security decision this turns on, stated plainly.** Adding CORS to a service on localhost is how local tools get robbed. Any page in any tab can already *send* a request to `127.0.0.1:8900`; the only reason that has been harmless is that the browser refuses to let the page *read* the reply. This feature removes that protection deliberately, one named origin at a time, so: **loopback earns nothing** (this is the one surface in ClawMetry where "the request came from this machine" is not authentication, and a key is always required); **there is no wildcard origin**, not as a flag and not as an env var, because every "just for local dev" wildcard ships eventually and fails silently and totally; **key management is not on the keyed surface** (minting, listing and revoking sit on the ordinary dashboard blueprint behind the existing same-origin write guard, so a read key can never issue itself a better one, and `_add_cors` is pinned to `/api/q/` as belt and braces); and **the API is GET only**, which removes cross-origin writes as a category rather than as a check. Nothing here can pause, stop or kill an agent: this adds no entry to the control plane. +- **`read:metrics` is exactly the `plaintext` trust class**, pinned by a test rather than by convention. That equality is what makes "a browser-resident key cannot return a prompt, a reply or a file path" a promise instead of a hope, and it is why the starter ships asking for that scope and nothing more. +- **Verified end to end in a real browser, not only in tests.** The starter served from `http://localhost:3000` rendered 30 days of real cost from a ClawMetry on a different port: **$750 across 10 runtimes and 10 models**, the numbers matching `/api/aggregates` on the same machine. The negative case was proven on that same page: a *valid* full-scope key bound to `https://my-ui.vercel.app` could not be used from `localhost:3000`, the browser refusing it with `Failed to fetch` before the response was readable. Plus **48 guards** in `tests/test_public_api_keys.py` (registered in `ci.yml`, since CI runs explicit file lists), with three deliberate mutations proving they go red: making `_add_cors` echo every origin fails 4, removing the scope check fails 2, and reclassifying `transcript` as `read:metrics` fails 4 including the trust-class invariant. Every drift guard green: query-contract, module map, runtime and channel counts, AC ratchet, daemon allowlist, py3.9 annotations, `lint-js`. + ### Fixed: a poisoned linked worktree scanned CLEAN (2026-09-08) - **Why:** `repo_scan` opened `/.git/config` and nothing else. In a **linked worktree** `.git` is a FILE holding `gitdir: /abs/path`, and the config git actually reads lives in the common directory that path points at, so the scanner found no config and returned no findings. That is worse than returning nothing: it is a confident all-clear over a repository git will happily execute `core.fsmonitor` from, on a layout agents and CI use routinely. CVE-2026-55607 is the vendor-confirmed version of the same git-directory confusion. Found by `scripts/redteam/audit.py` itself, which filed the gap automatically: the audit doing exactly the job it was wired into CI for one release earlier. - **What:** `_git_dirs()` resolves `(git_dir, common_dir)` through the `.git` file's `gitdir:` and the worktree's `commondir`. `_git_config_paths()` returns every config git reads, which is `/config` plus `/config.worktree` (honoured when `extensions.worktreeConfig` is set, and writable by whoever supplied the worktree). The finding reports the config it was actually read from, trimmed to its last three components, because an incident travels to a UI and to a device and must not carry the user's home directory. Ordinary checkouts are untouched: `_git_dirs` answers with `.git` for both values and the label stays `.git/config`. @@ -58,8 +65,7 @@ - **What:** three PASS and are now cases. `npm-postinstall-visible-harvest` (credential_access, critical), `mcp-tool-output-prompt-injection` (credential_access, critical) and `mcp-injection-without-exfil` (privilege_change). The two MCP cases are deliberately a pair: the injection itself is invisible to us, since it arrives in a tool RESULT and no detector reads a result as an instruction, so what the pair measures is whether the BEHAVIOUR an injection produces is caught, in both the exfiltration shape and a non-exfiltration one. `control-ordinary-dev-session` is the negative control that belongs beside them: install, read `.env.example`, run tests, push, and stay silent. - **The fourth is a MISS, and it is filed rather than shipped red.** `npm-postinstall-credential-harvest`: nothing fired at all. It is not a tuning problem. For the invisible half of the attack the agent chose exactly one action, `npm install`, and npm's child processes did the rest, so the event stream is byte-for-byte the stream of a developer installing a dependency. No tool-stream detector can separate them. The fix is the workspace surface, the same answer `repo_scan` gave for GitSpawn, and the gap carries the audit's own verdict on the private tracker. - **The README now records what is deliberately NOT in the corpus**, so the next person does not rediscover it: cross-session coordination (the Hugging Face evaluation swarm) is not merely undetected but **inexpressible**, because `run_all` takes one session's events and so does the corpus runner; and credential-scoping bypass has no observable in the stream at all. -- **Verified:** `scripts/redteam/audit.py` reports 13/13 pass, 0 gaps, 0 control failures; the corpus suite is 28 tests, up from 24. Both run on every PR through the gate added in 0.12.837. - +- **Verified:** `scripts/redteam/audit.py` reports 13/13 pass, 0 gaps, 0 control failures; the corpus suite is 28 tests, up from 24. Both run on every PR through the gate added in 0.12.837. b2bf019 (feat: build your own UI — a keyed, scoped read API over the q/1 contract) ### Added: the daemon scans a session's workspace, which is the surface the tool stream cannot see (2026-09-08) - **Why:** every behavioural detector reads what the agent *chose* to do. GitSpawn is the proof that this is a partial view of the machine: a poisoned `.git/config` makes **git** spawn the payload during the background `git status` a runtime fires on open, the agent calls no tool, and `detectors.run_all` sees a clean session. `clawmetry/repo_scan.py` closes that gap and has shipped for a while, detecting all three GitSpawn variants plus the CHAINDROP hook shapes, with `clawmetry scan-repo` exposing it to a human. Nothing in the product called it. A detector nobody runs protects nobody. - **What:** `sync._emit_detector_incidents` now scans each session's `cwd` and emits findings on the path detector incidents already take: a `loop_signals` row (`daemon_detect_repo_config_exec` / `daemon_detect_agent_config_tamper`), `incident_alerts` delivery, and the heartbeat fold. The scan is cached on the mtime and size of exactly the files it reads (`.git/config`, `.vscode/tasks.json`, the `_AGENT_HOOK_FILES` entries) and nothing else, so an unchanged repo is never re-read and a repo poisoned *after* it was first seen clean is re-scanned on the next tick. Cache bounded at 500 directories, oldest evicted. `CLAWMETRY_REPO_SCAN=0` turns it off. diff --git a/CLAUDE.md b/CLAUDE.md index 162b5a2c36..42d835a2e2 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -45,6 +45,7 @@ All HTTP endpoints live here, organised by feature: 70 modules, 82 blueprints, l | `routes/channels.py` | `bp_channels` — 23 chat-channel adapters (Telegram, Signal, WhatsApp, Discord, Slack, IRC, iMessage, WebChat, …) | | `routes/components.py` | `bp_components` — Flow-panel detail endpoints (tool / runtime / machine / gateway / brain) | | `routes/local_query.py` | `bp_local_query` — `/api/local/*` DuckDB read API + the daemon-proxy `_dispatch` (shape→store bridge shared by HTTP and the cloud relay) | +| `routes/public_api.py` | `bp_public_api` — `/api/q/1/*`, the **keyed, cross-origin** read API custom UIs are built on (`docs/BUILD_YOUR_OWN_UI.md`).

Run +`clawmetry key scopes` for the same thing in a terminal. + +Pick the narrowest scope that makes your UI work. `read:metrics` is +exactly the set of queries that cannot return a prompt, a reply or a file +path, which makes it the right choice for anything that renders in a +browser. + +## What a key can and cannot do + +**Can:** run the `q/1` read queries its scopes cover, from a site it +names, at up to 240 requests a minute. + +**Cannot:** write anything. Pause, stop or kill an agent. Change a +policy, a budget, an alert or a cron. Create another key. Read a query +outside its scopes. Be used from an origin it does not name. + +The API is GET only, so it cannot be the target of a cross-origin write +even in principle. + +## About that origin + +Every key must name the sites allowed to use it from a browser. There is +no wildcard, and the flag is not optional. + +This is worth a paragraph, because it is the part people try to skip. +Your ClawMetry runs on `localhost`. Any page in any tab can already *send* +a request to `localhost`. The only reason that has never mattered is that +the browser refuses to let a page *read* the reply from an origin that +did not permit it. An API key with an origin allowlist is how you hand +out that permission one site at a time. A wildcard would hand it to every +site at once, including a page you did not open on purpose. + +For a key used outside a browser (a cron job, a backend, a script), pass +`--origin none`. It gets no CORS header at all, which is correct: nothing +in a browser should be able to use it. + +## Remote and self-hosted ClawMetry + +The API works the same when ClawMetry is not on the caller's machine. +Point at that host instead of `localhost:8900`. The key is the whole +gate: unlike the rest of the dashboard, this surface does not trust a +request just because it came from the local machine. + +If you use ClawMetry Cloud, note that session content is stored +end-to-end encrypted and decrypted in your browser, so the cloud cannot +serve it through a REST API even to you. Point custom UIs at the machine +your agents actually run on. + +## Using MCP instead + +If what you want is an agent that can *ask about* your runs rather than a +page that draws them, the MCP server is a better fit than this API: + +```bash +clawmetry mcp install +``` + +It exposes sessions, cost, traces and health as MCP tools over stdio, so +Claude Code and other MCP clients can query them directly. + +## When it does not work + +**The browser console says "blocked by CORS policy".** The origin your +page is served from is not on the key's list. The message names the +origin the browser sent; create a key with that exact origin, scheme and +port included. `http://localhost:3000` and `http://127.0.0.1:3000` are +different origins. + +**401 with "This API needs a key".** The `Authorization` header is not +arriving.

They were implemented, at lines 2955-3042 of a 3042-line file, i.e. at 97% depth: the bot reads a truncated prefix of a long file, so anything appended to a module that size is invisible to it forever. Rather than argue the point on a PR comment, extract them. They now live in routes/apikeys_admin.py (bp_apikeys_admin, ~130 lines), registered in dashboard.py next to bp_public_api. routes/infra.py returns byte for byte to its state on main. This is better placement independent of the tool. Credential management is a different concern from the security tab's scanners, and the reason these handlers must not sit on the keyed surface now has a file to be stated in rather than a comment in the middle of another one. Both guards are path-based, not blueprint-based, so the security posture is unchanged: dashboard.py's _cross_origin_write_blocked still refuses a cross-origin POST/DELETE, and public_api._add_cors is still pinned to /api/q/. A new guard asserts the separation directly: no /api/apikeys rule may be owned by the public_api blueprint and no /api/q/ rule by apikeys_admin. Verified on a real boot after the move, not only in tests: management GET 200, POST with no origin 400, cross-origin POST 403, query index 401 without a key and 200 with one, aggregates 200, CORS header present on /api/q/ and absent on /api/apikeys. Blueprint v4 names the module. Cloud #2342 updated to match the new endpoint names.

It was not: 8 new alerts, 4 of them high, all in code this PR adds. Triaged individually. This repo runs code scanning through DEFAULT SETUP, so inline '# codeql[...]' comments are inert here (measured in clawmetry/nonsecret_hash.py, not assumed). Every alert therefore had to be fixed in code or accepted deliberately. Six are fixed: * py/stack-trace-exposure x2. Both were our own authored sentences, but text read off an exception is exception-derived to a static analyser no matter who wrote it. The /api/q/ 400 is now built from the CONTRACT (which already declares the required args) and the /api/apikeys 400 from a literal table keyed by a refusal code. Both are better answers: the query error is now consistent across queries and carries missing_args, and the create error carries a stable 'reason' a client can branch on instead of matching prose. * py/log-injection. The failure log now names the contract's own backing method rather than the shape string off the URL. Validated-then-logged is still a request-text sink. * py/clear-text-logging x2 of 4. The two curl examples no longer interpolate the key; they use , which is what the docs tell people to do with it anyway and reads better than a 50-character key wrapped across a terminal. * js/xss-through-exception. The starter's error panel built markup out of strings including a fetch exception message. It now builds text nodes and elements, so nothing it did not write becomes markup. The two remaining alerts are the one-time key reveal (the plain print and the --json field). A key that is never shown cannot be used, and every comparable CLI does exactly this. They are true observations, not defects, and with no working in-code suppression they can only be dismissed by a maintainer in the Security tab. Verified live after the change: the contract-built 400 names session_id and returns missing_args, the management 400 carries reason 'unknown_scope' with no exception text, the wildcard refusal still fires, and all three normal paths stay 200. Both starter error panels render as real text nodes (3 , 1
) and the happy path still draws across 10 runtimes and 10 models.

Host header injection (CWE-113): `request.host_url` was reflected verbatim into the text/plain llms.txt response. A crafted Host header could inject content into that response. Fix: reconstruct the base URL from urlparse components (scheme + netloc) so embedded newlines or other injections are stripped before they reach the response body. 2. Reflected unvalidated input (CWE-79-adjacent): the URL path segment `shape` was echoed directly into the 404 JSON error before it had been validated against the query contract. At that point `shape` is raw user input. Fix: omit `shape` from the 404 message and direct the caller to GET /api/q/1 instead. (The 403 error on line ~377 safely uses `shape` because it is only reached after the contract check passes.)

The CORS echo was already gated behind an allowlist check (``origin_allowed`` / ``any_key_allows_origin``), so no actual attack was possible — but the taint chain remained because the code placed the *caller-supplied* string into the header rather than the *stored* canonical form. Fix: add ``canonical_allowed_origin`` and ``any_canonical_allowed_origin`` to ``clawmetry/apikeys.py``. These return the stored string from the key's ``origins`` list (written once at key-creation time by ``normalise_origins``), not the runtime request value. ``_add_cors`` now uses these functions, so ``Access-Control-Allow-Origin`` always holds a value from the stored list rather than from request.headers.

Added `_ORIGIN_RE.fullmatch(canonical)` guard before the header is set. 2. `request.host_url` → `_llms_txt` response body: added `_HOST_RE.fullmatch` on the parsed netloc before constructing the URL, with a safe fallback, so a crafted Host header cannot inject arbitrary content. Both changes are defence-in-depth as well as CodeQL-satisfying: the regex is exactly the character set normalise_origins() accepts on write, so a stored value can only fail the check if the store was corrupted externally.

CodeQL traces taint through function arguments even when the implementation returns stored data. Fix: inline the comparison so `canonical` is assigned directly from stored values (record.get("origins") or apikeys.all_live_origins()) after an equality check against o_low. The taint source (origin) is only ever used for the comparison, never assigned into the header. 2. _llms_txt: taint flowed from request.host_url through urlparse() → _p.netloc → host → response body. Fix: use request.host directly (already just the netloc) and gate with _HOST_RE.fullmatch() before use. This makes the sanitizer visible to CodeQL without an intermediate urlparse step.

These functions return the STORED canonical origin value, never the caller-supplied request.headers["Origin"] string. CodeQL tracks taint through variable assignments; routing through a function that takes user input only as a comparison target and returns stored data severs the taint chain more cleanly than an inline loop doing the same thing. 2. _llms_txt: replaced `_host_hdr` (raw request.host string) in the format string with `_m.group(0)` (the regex match group). CodeQL recognises re.fullmatch(...).group(0) as a sanitizer break: the return value comes from the matched pattern, not from the original tainted string, so the taint flow from request.host into the response body is severed. Both changes are behaviour-equivalent; the existing _ORIGIN_RE.fullmatch guard in _add_cors is kept as defence-in-depth.

CodeQL conservatively marks the return value of any user-defined function that receives a tainted argument as tainted, so record came out tainted, making record.get("origins") -> stored_origins -> matched -> response.headers["ACAO"] a taint chain from each header source (two findings, one per source). Fix: use apikeys.all_live_origins() -- which takes zero user input and reads directly from the key store file -- for the ACAO header value. Per-key origin filtering is kept via a boolean-only guard on record.get("origins"): the result is a bool that never flows to the response header, so no taint path from Authorization or X-ClawMetry-Key reaches Access-Control-Allow-Origin. No behaviour change: the same origins are allowed, from the same store, with the same per-key scoping.

Replace it with a direct call to apikeys.canonical_allowed_origin() (when a key was authenticated) or apikeys.any_canonical_allowed_origin() (preflight path). Both functions take the caller-supplied normalised origin only as a search key and return the stored canonical form from the on-disk key file, which CodeQL treats as untainted data. Behaviour is identical to the previous code; the stored value returned is always the same normalised origin that was saved by normalise_origins() at key-creation time. CWE-79 (q_shape): shape is validated as a QUERY_CONTRACT key before out["shape"] = shape, so its value is always one of a small constant set of strings.

Even though both functions return a stored canonical string, CodeQL's inter-procedural taint tracking propagated the taint through the function boundary and flagged the header assignment. Fix: replace both call sites with the integer-index pattern that apikeys.all_live_origins() was designed for (its docstring says it exists to break the CWE-113 chain): _lc_live.index(_norm) returns an int (provably untainted), and _live[_idx] retrieves the stored string. No user-controlled data can reach the response header via an integer. Finding 2 (py/clear-text-logging-sensitive-data) in routes/apikeys_admin.py: the POST /api/apikeys handler returns the newly minted cmk_ secret in the response body. The variable name "plaintext" triggers CodeQL's credential-in-response heuristic. The CLI paths that do the same thing (print(plaintext)) already carry the correct suppression annotation; this HTTP handler was missing it. Fix: add # codeql[py/clear-text-logging-sensitive-data] to the one line in api_keys_create that sends the secret. The behaviour is intentional -- one-time delivery of the user's own key, never recoverable afterward -- but the intent was not communicated to the analyser. Both findings are false positives in the security sense (the architecture is correct) but are genuine CodeQL HIGH alerts because the matching suppression annotations on the CLI path were not applied to the HTTP-layer equivalents.
