* fix: enforce a replay window on Linear webhooks (AUTHZ-001)
verify_linear_signature accepted any correctly-signed body with no freshness
check, so a captured request could be replayed indefinitely. Parse the
signed webhookTimestamp (Unix ms) and reject requests outside a 60s window,
failing closed when the field is missing or malformed — mirroring the Slack
verifier.
* fix: stop leaking upstream auth-error bodies into user comments
get_github_token_for_user folded the raw upstream response text into the
error string that becomes a Slack/Linear comment (AUTH-RESP-LEAK-01). Log the
full body server-side only and return a generic "GitHub auth failed (status
<code>)". Also document the accepted shared-installation-token blast radius on
the bot-token-only path (AUTHZ-003).
* fix: bind sandbox and token caches to repo to prevent thread-id collision
A PR head-branch name is attacker-controllable and get_thread_id_from_branch
derives a thread_id from its first UUID with no repo binding (TID-COLLIDE-01).
The in-memory sandbox cache and the per-thread GitHub-token cache were keyed on
thread_id alone, and a cached sandbox was reused after only an echo-ping, so a
different repo's webhook could bind to another thread's sandbox or token.
Without changing the persistent thread-id scheme:
- Persist the bound repo (owner/name) in thread metadata on sandbox creation and
refuse to reuse a sandbox whose bound repo does not match the current event
(SandboxRepoMismatchError); the in-memory proxy also carries the binding.
- Bind the GitHub-token cache entries to their repo and evict on a cross-repo
read so a colliding thread_id cannot be served another repo's token.
- Thread repo through the reviewer and the webhook token resolvers.
* fix: scope s3:ListBucket to the releases/ prefix (F-1/IAC-04)
The instance role and the GitHub deploy app role granted s3:ListBucket on the
whole assets bucket. Every caller (deploy.sh, the publish/rollback scripts)
only ever lists under releases/, so add a StringLike s3:prefix=releases/*
condition. GetBucketLocation has no s3:prefix in its request context, so it
moves to its own unconditioned statement. Also document the accepted F-2
cross-env existence-oracle residual on BatchGetSecretValue.
* chore: suppress test-fixture credential false positive; document AUTHZ-002
Add a machine-level suppression for the fake Datadog key in the
test_team_credentials encryption-roundtrip fixture (CWE-798, not a real
credential). Clarify that the within-org thread-write path is intentional by
design (AUTHZ-002) — comment only, no behavior change.
* fix: casefold repo-binding keys to avoid spurious cross-repo mismatch
GitHub owner/name are case-insensitive. Casefold the owner/name key on both the
write (binding) and read (compare) sides — repo_cache_key and the metadata
bound_repo read — so Org/Repo and org/repo resolve to one repo and a legitimate
same-repo run cannot raise a spurious SandboxRepoMismatchError (Gap 2).
* fix: stop leaking upstream auth body in unexpected-result branch
The 2xx-but-missing-token/url branch echoed the parsed upstream response body
into the user-facing error. Return a generic message and log response_data
server-side only, mirroring the existing HTTPStatusError fix (Gap 4).
* fix: fail closed for unbound-legacy sandboxes and catch repo mismatch
Gap 1: a thread with a persisted sandbox_id but no in-memory cache and no
recorded bound_repo (a pre-binding legacy thread, post-deploy) previously
reconnected-and-served the sandbox to the current repo, then rebound it. Now
fail closed: drop the stale id and recreate a fresh sandbox bound to this repo,
logging a reconnect-with-missing-binding event. A sandbox is never served to a
repo unless its binding is known and matches; new threads bind on first run
unchanged.
Gap 3: catch SandboxRepoMismatchError at the agent and reviewer run entrypoints,
log it for alarming, and surface a clean sanitized error instead of letting an
opaque deep-stack exception crash-loop the worker.
* chore: suppress test-fixture credential false positive in token-TTL tests
Add a machine-level suppression for the fake "ghp_secret" GitHub token used by
the cached-token TTL/revocation unit tests (CWE-798). Not a real credential and
not a valid PAT; scoped to the unit test only.
* feat: TTL and revocation handling for cached GitHub OAuth tokens [closes AB-2322]
Persist github_token_expires_at alongside github_token_encrypted, treat
expired cache entries as missing so we re-resolve before kicking off
runs, and invalidate the cached ciphertext on a downstream 401 so the
next invocation gets a fresh token instead of replaying a revoked one.

* webapp: forward installation-token expiry to reviewer cache writes
The three reviewer-thread persist sites in webapp.py were calling
get_github_app_installation_token() (no expiry) and persist_encrypted_github_token
without expires_at, so cached App tokens were treated as never-expiring even
though they actually expire in ~1 hour.

Calling get_github_token() without arguments always invoked LangGraph get_config internally,
which broke tests that only patch agent.middleware.open_pr.get_config and failed outside
runnable context.
Extend get_github_token with an optional runnable config mapping; the middleware passes
the config dict already resolved from get_config(). Request GitHub App installation tokens
only after detecting sandbox/repo changes worth publishing.
Fixes failing Agent unit tests in tests/test_open_pr_middleware.py.
