Canonical OpenAI PATCH allows allowPrivateNetwork bypass via matchesCanonicalProviderSeed.
The matchesCanonicalProviderSeed function at lines 616–619 validates only keys present in the registry seed. Because the canonical OpenAI seed does not define allowPrivateNetwork, a PATCH request can inject allowPrivateNetwork: true without triggering the canonical seed check. This field is not deleted from the validation candidate (unlike pinnedReasoningEffort, modelCosts, requestPacing, etc.), so it passes through to persistence. Downstream code in providerDestinationConfigError and providerDestinationResolvedError then consults this persisted flag to permit private-network destination access, enabling SSRF to internal metadata endpoints or RFC 1918 addresses.
Add allowPrivateNetwork to the field deletions for canonical OpenAI before the seed comparison, and cover the PATCH path with a regression test to prevent this field from being smuggled into canonical providers.
Proposed fix
// Same category: annotating empty tool outputs is a user-owned request-shaping preference,
// not part of the canonical transport seed. Without this the field is accepted by
// validation and then rejected by the seed comparison, so canonical OpenAI could never
// set OR clear it — the value was admitted and then refused in the same request.
delete canonicalCandidate.annotateEmptyToolOutputs;
+ // allowPrivateNetwork is an explicit operator opt-in for non-registry destinations.
+ // Canonical OpenAI must never include it; reject any attempt to smuggle it via PATCH.
+ delete canonicalCandidate.allowPrivateNetwork;

…-availability Lane B of the contributor carry train: truncated-terminal search failure (#4381 by luvs01), bounded bridge iteration buffering (#4388 by luvs01), and distinguishing model availability from auth failure (#4460 by AgenticLab-SH). Tip-only CI by owner authorization for this batch. Cross-platform CI run 34744793611 concluded success on bd39d3b, the exact head merged here, and it covers every link because the lane is cumulative. #4472 and #4478 carry no ci check of their own. Lane S (#4477, carrying #4447) is deliberately not part of this lane and is held for maintainer security review.
…i-overlays Lane S of the contributor carry train, released from its security-review hold. Carries #4447 by Veritas-7: merge-based provider writes (PATCH, the provider editor, reload) no longer fail the canonical-seed comparison because a persisted operator overlay such as selectedModels rides along in the merged candidate. Seed keys stay byte-pinned and POST keeps the strict exact-key comparison. Maintainer security review is recorded in the pull request thread and changed the outcome. The review found that the canonical OpenAI seed defines only four keys, so overlay tolerance reaches nearly every config key, and that headers was a live gap: the PATCH field mask writes it, and the forward adapter applies provider.headers to the upstream ChatGPT request before the incoming forward headers, so a persisted value wins whenever the caller omits that header. c39098b denies headers on canonical openai the way allowPrivateNetwork is denied, with a regression test that was driven red before it was accepted. Cross-platform CI run 34748483096 concluded success on c39098ba3d98d1f2fa4c6b1c4c3f9c0e1e2f0a4b, the exact head merged here. Its first attempt failed in the select-windows-runner job with no failing step, which is a runner-allocation flake rather than a code failure; re-running the failed jobs on the same commit turned the run green, so the evidence remains exact-head. Recorded follow-up, not blocking: the overlay tolerance is a denylist. A future provider field classified editor that touches a trust boundary would become silently reachable on the canonical row, and codexToolMode is the current example. The durable fix is an explicit overlay allowlist plus a guard test.

Closing as landed, with your fix on dev and your credit attached. The carry is #4477, merged as 981b53e and verified as an ancestor of origin/dev. Your Your diagnosis held up under review. Two things changed on the way in, and one of them matters for the security story. Your The review found one more field in the same class that the deny did not cover.

…tored overlays Carry lidge-jun#4447 from ed96552 onto origin/dev. PATCH /api/providers, the provider editor, and reload merge onto the persisted row. Once selectedModels (or disabled, or any other operator overlay) is on disk, the exact-key canonical seed check rejected every later field-masked write with "must equal the canonical built-in provider seed". Keep that exact-key comparison for POST. Merge-based paths now require every seed-defined key to match and ignore keys the seed never defines. Fold the source review finding: overlay-tolerant comparison would otherwise let allowPrivateNetwork persist on canonical openai and short-circuit destination DNS checks (loopback, RFC1918, metadata). Canonical openai still rejects that field. CodeRabbit's proposed delete-from-candidate would have allowed persistence; this rejects it. Source PR targeted main; this carry lands on dev. The source pull request is left alone. Local product suite, build and install: NOT RUN. Hosted exact-head CI on this PR is the merge proof.

Plan the carry of the 16 open contributor pull requests scored 60 or higher and the 8 unowned 60+ issues into dev, as eight wave-1 lanes and three wave-2 lanes. Two grok-4.6 reviewer passes gated this roadmap. The first returned FAIL on five blockers: H and I4 were prepared as peers though both write the routed Responses path, lidge-jun#4447 carried a security-review hold in one document while another tip-merged the lane containing it, lane I1 claimed a Windows CI leg that is workflow_dispatch-only, the core.ts toucher count called an issue a pull request, and the candidate table omitted lidge-jun#4409. All five are folded here; the second pass returned NEAR-PASS and its three wording residuals are folded too.

Summary
PATCH /api/providers?name=openaifails withprovider openai must equal the canonical built-in provider seedas soon as the stored provider row carries any operator overlay — most commonlyselectedModels, which the Models page (/api/selected-models) writes onto the provider.Once that happens, every field-masked write to the built-in OpenAI provider is bricked:
modelContextWindows,disabled,defaultModel, headers, etc. all return 400, even though the overlays themselves were admitted by their own write boundaries and cannot widen what the forward proxy claims.Root cause
providerManagementConfigErrorguards the canonical OpenAI transport/auth surface withsameCanonicalProviderSeed, an exact key-set comparison between the submitted provider and the built-in registry seed.That strictness is right for full-object writes (
POST /api/providers), where an overlay riding on a canonical seed must still be rejected.But the merge-based write paths —
PATCH /api/providers, the provider editorPUT, and the provider reload path — validate a candidate that was merged onto the persisted row. Once an overlay lands on disk, every later candidate carries that extra key and fails the exact-key check.Fix
Add an
allowOperatorOverlaysmode toproviderManagementConfigErrorthat keeps the seed check strict on every key the seed defines (missing key or value mismatch still fails), while ignoring keys the seed never defines. The merge-based paths (PATCH, editor PUT, reload) opt in;POSTkeeps the exact-key comparison.Repro
Two regression tests added:
selectedModelsrow can still PATCHmodelContextWindows, and transport tampering (baseUrloverride) is still rejected on the same row.Testing
