Severity HIGH. #318 closed the fake-UUID fail-open for WorkspaceAuth
but left the grace period intact for *real* workspaces with no live
tokens. Zombie test-artifact workspaces from prior DAST runs still
exist in the DB with empty configs and no tokens, so they pass
WorkspaceExists=true but HasAnyLiveToken=false — and fell through the
grace period, leaking every global-secret key name to any
unauthenticated caller on the Docker network.
Phase 30.1 shipped months ago; every production workspace has gone
through multiple boot cycles and acquired a token since. The
"legacy workspaces grandfathered" window no longer serves legitimate
traffic. Removing it entirely is the cleanest fix — and does NOT
affect registration (which is on /registry/register, outside this
middleware's scope).
New contract (strict):
every /workspaces/:id/* request MUST carry
Authorization: Bearer <token-for-this-workspace>
Any missing/mismatched/revoked/wrong-workspace bearer → 401. No
existence check, no fallback. The wsauth.WorkspaceExists helper is
kept in the package for any future caller but no longer used here.
Tests:
- TestWorkspaceAuth_351_NoBearer_Returns401_NoDBCalls — new, covers
fake UUID / zombie / pre-token in one sub-table. Asserts zero DB
calls on missing bearer.
- Existing C4/C8 + #170 tests updated to drop the stale
HasAnyLiveToken sqlmock expectations.
- Renamed TestWorkspaceAuth_Issue170_SecretDelete_FailOpen_NoTokens
to _NoTokensStillRejected and flipped the assertion from 200 to 401.
- Dropped TestWorkspaceAuth_318_ExistsQueryError_Returns500 — the
code path it covered no longer exists.
Full platform test sweep green.
Closes#351
