This results in a scenario where an access token that was introspected immediately before a revocation request may be returned again to the client after revocation, until the relevant cache entry is cleared.\n\nThe security consequence is that a revoked access token may be re-issued to the client during the cache lifetime. While the re-issued token is not treated as valid for API authorization, affected users may be unable to obtain a new valid access token until the cache is cleared, which can disrupt authentication flows.","state":0,"publishedAt":"2026-10-28T19:21:34.577+00:00","modifiedAt":"2026-10-29T02:02:14.134+00:00","affected":[{"ecosystem":"Vendor product","name":"WSO2 API
