The handler filters candidates by admission scope before Pool credential resolution, validates outbound Authorization, and releases probe leases on specified failure and cancellation paths.

Merge Risk: 🔵 Low · up to The planning comments do not block merge, but malformed Pool credentials may still reach an upstream Images request. Resolve that existing concern or explicitly accept the bounded risk before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new route appears to keep the caller’s bearer out of upstream requests and checks key scope before selecting a Pool account. Cancellation during account credential resolution remains a boundedness concern: a canceled request may continue that work until resolution finishes. Retained concerns

When a configured scoped key is supplied as the bearer—the path newly made Pool-eligible here—this call resolves or refreshes the stored OpenAI credential before admissionScopeDenial runs. If the selected Pool credential is missing or invalid, the handler returns its 401 without ever applying the key's provider/model scope; if refresh is needed, a key forbidden from OpenAI can also initiate credential I/O and account-state changes before eventually receiving 403. Apply the scope before Pool credential resolution, while preserving any later check needed for a destination selected by fallback.

Fixed in 46515c2 (now part of ad40e8d). handleImages filters forward candidates by the key's provider/model scope before resolveFirstUsableOpenAiSidecar, so a forbidden key never resolves, refreshes or leases a stored Pool credential. When no allowed destination remains and CCA does not serve the request, the scope 403 is returned ahead of the generic configuration 400. The post-resolution check stays as defence in depth. Regression fixtures in tests/server/server-images-pool-admission.test.ts: forbidden Pool scope returns 403 with no credential stored (Pool-first ordering would return 401) and zero sends; an allowed Pool scope still sends with the Pool bearer; a key scoped only to the keyed provider reaches the keyed branch without Pool resolution. The first and third were red on the previous head.

| The original PR authors are @rrmlima (#5927) and @hulkbig (#5497); carried commits need `Co-authored-by` trailers. Each original PR receives a link and thanks after its replacement lands. A rejected-but-viable PR stays open with a concrete English reason. Closed issues require a merged dev fix and a comment linking the merge. Existing issue comments for #3506, #5270 and #2511 already explain their core limitations; the train-4 disposition will link or update them only where new evidence changes it. |

This line records that the change carries #5927 and requires a Co-authored-by trailer, but the reviewed commit has no trailer: its message only mentions Co-authored-by: Rafael Moreira <rrmlima@gmail.com> inline in a Summary bullet. GitHub does not recognize that prose as attribution, so the carried author's contribution remains absent from the contributor graph; add a genuine trailer to the landing commit or squash message.

The implementation commit acc750effa carries a genuine trailer (git show acc750effa --format=%B ends with Co-authored-by: Rafael Moreira <rrmlima@gmail.com>), and both follow-up commits repeat it. The squash message will keep it as a standalone trailer.

리뷰 · 우선순위 66 / 80이 PR은 프록시 입장 토큰으로 들어온 이미지 요청이, 저장해 둔 Pool 계정으로 그림을 만들 수 있게 해요. 예전에는 입장 토큰이 오면 ChatGPT로 넘기는 길을 전부 막았어요. 그 토큰을 그대로 업스트림에 붙이면 안 되기 때문이에요. Pool에 로그인해 둔 계정이 있어도, 클라이언트가 opencodex 키로만 인증하면 이미지 요청은 Pool을 못 탔어요. 이제는 Direct만 막아요. Direct는 호출자가 보낸 토큰을 그대로 쓰니까, 입장 토큰을 넘기면 안 돼요. Pool은 저장된 계정 토큰으로 바꿔 보내요. 그 토큰이 깨져 있으면 돈을 내는 요청을 보내기 전에 거절하고, 잡아 둔 프로브 잠금도 풀어요. 선택된 계정 토큰만 Authorization에 남아요. 설정에 다른 Authorization이 있어도 덮어써요. Pool 로그인이 실패하면, 따로 과금되는 API 키로 넘어가지 않아요. 테스트는 새 파일 src/server/images.ts:710 - Pool 자격 증명을 고르고, 필요하면 갱신하는 일이 키 범위 검사(749)보다 먼저 돌아요. OpenAI를 금지한 키도 Pool 계정 상태를 건드려요. 자격 증명이 없으면 775에서 401을 돌려주고, 403 범위 거절은 보지 않아요. 기존 범위 테스트는 Pool 계정이 없는 설정이라 이 순서를 잡지 못해요. src/server/images.ts:730 - sidecar가 던진 TypeError는 전부 "자격 검증 실패" 500으로 끝나요. 범위 검사와 키 제공자 길로 내려가지 않아요. 헤더 값이 깨진 경우만 잡으려는 자리인데, 다른 TypeError도 같은 응답이 돼요. src/server/images.ts:743 - 주석은 가지에 들어가기 전에 자격 증명을 풀지 않는다고 적혀 있어요. Pool은 710에서 이미 풀어요. 메인테이너의 판단이 필요한 지점 입장 토큰으로 Pool을 여는 방향은 맞아요. 범위 있는 키가 Pool 갱신보다 먼저 403을 받아야 하는지 정해 주세요. 받아야 한다면 710 앞에서 CodeRabbit은 콜론이 든 Pool 토큰도 거절하자고 했어요. 지금 식은 공백이랑 쉼표만 막아요. sidecar가 호출자 Bearer를 읽을 때 쓰는 식과 같아요. 콜론까지 막을지는 새 규칙이에요. 너의 추천 머지 전에 범위 검사를 Pool 조회보다 앞으로 옮겨 주세요. Pool 자격 증명이 없을 때도 401보다 403이 먼저여야 해요. 그 경우를 새 픽스처에 하나 넣어 주세요. TypeError는 헤더를 만들다 난 것만 500으로 두고, 나머지는 그대로 올려 주세요. 이 PR이 이 댓글은 grok-bot이 작성했습니다 |

Carry the scoped provider-owned Images fix from #5927 onto current dev. Keep Direct ineligible for a proxy admission bearer, give the selected upstream credential sole Authorization ownership, and fail before a paid send on invalid credentials. Co-authored-by: Rafael Moreira <rrmlima@gmail.com>
A scoped admission key reached Pool credential resolution before admissionScopeDenial, so a key forbidden from OpenAI could trigger credential refresh and account-state changes and received Pool's 401 instead of the scope 403. Forward candidates are now filtered by the key scope first; the post-resolution check stays as defence in depth. Co-authored-by: Rafael Moreira <rrmlima@gmail.com>
