{"id":"CVE-2026-3583","published":"2026-10-28T20:17:24.340","lastModified":"2026-10-29T04:18:36.017","description":"When the `allowed_scopes` configuration is enabled, the OAuth2 token introspection mechanism does not immediately invalidate a token in the cache after a revocation request. 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.","cvssScore":3.1,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-613"],"vendors":[],"products":[],"references":[{"url":"https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2026/WSO2-2026-5175/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
