📝 WalkthroughWalkthroughAdds a security-definer RPC for hashed API key regeneration. The RPC validates caller identity, ownership, and organization permissions before rotation. Tests cover unauthorized members, sibling keys, and successful regeneration by an organization administrator. ChangesHashed API key regeneration authorization
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The RPC now checks management permissions, but concurrent API-key binding changes can still bypass that check during rotation and expose a plaintext key to an unauthorized caller. Merge should be blocked until rotation is serialized with binding changes; the migration lint failure and weakened test typing also need correction. Sequence Diagram(s)sequenceDiagram

- Line 91: Wrap the long function comment string in the migration by splitting
it into adjacent concatenated SQL string literals, preserving the exact comment
text and meaning while ensuring each line satisfies SQLFluff LT05.
- Around line 10-16: Update the migration documentation for
public.regenerate_hashed_apikey(bigint) to include the worst-case supported
role_bindings cardinality and corresponding EXPLAIN (ANALYZE, BUFFERS)
query-plan evidence, including the per-distinct-org rbac_check_permission_direct
calls. Keep the existing execution-model and index details intact.
- Around line 52-80: Update public.regenerate_hashed_apikey to acquire a per-key
advisory lock or row lock before scanning role_bindings, and hold it through
regenerate_hashed_apikey_for_user so binding mutations and rotation are
serialized. Ensure concurrent binding additions cannot commit between
authorization and key update; add an integration test covering that race and
asserting the RPC aborts or re-authorizes.
In `@tests/hashed-apikey-rls.test.ts`:
- Around line 1036-1038: In tests/hashed-apikey-rls.test.ts at lines 1036-1038
and 1074-1076, import Database, instantiate the Supabase clients with
createClient<Database>(...), and remove the as any casts from all three
regenerate_hashed_apikey RPC calls, including the affected call near line 1110,
so RPC names, arguments, and return values use the generated types.

Summary (AI generated)
public.regenerate_hashed_apikey(bigint)so rotation requiresorg.manage_apikeyson every org the target key is bound to (GHSA-4h9w-86j7-q2p3).anon+authenticatedso capgkey PostgREST can still call it, but fail closed for read-only / unprivileged keys.PUT /apikeyunchanged; a sibling PR covers GHSA-8h52 rank checks.Motivation (AI generated)
The public RPC only checked that the caller shared
user_idwith the target key, then returned plaintext. Any API key owned by that user, including a read-only key, could rotate a sibling key and steal its privileges. HTTP already requiresorg.manage_apikeysand uses the service-role helper; this PR closes the same hole on the compatibility RPC.Business Impact (AI generated)
Stops privilege theft through the public hashed-key rotation RPC. Console and CI callers that already have
org.manage_apikeyskeep working. Read-only keys can no longer mint a higher-privilege plaintext key.Test Plan (AI generated)
org_memberhashed key cannot rotate itself viaregenerate_hashed_apikeyorg_adminkey via the RPCorg.manage_apikeys(org_adminkey) can still rotate its own non-super-admin key and use the new plaintexttests/hashed-apikey-rls.test.tspassed locally (43 tests)Screenshots (AI generated)
Not applicable. SQL RPC + backend tests only. No UI change.
