Summary
Deleted API tokens continued to authenticate requests until their cache entry expired, because the auth cache was not invalidated by token value at deletion time.
Details
The API token deletion path removed the database row but did not evict the token-value keyed entry from the auth cache. The auth middleware therefore continued to accept the deleted token until the cache entry aged out, leaving a deletion-to-revocation window of up to three days.
Impact
Tokens revoked through the UI or API continued to grant access during the cache TTL, breaking the operator's expected security guarantee that deletion is immediate.
