CVE-2026-3583 is a low-severity flaw (CVSS 3.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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. The security consequence is that a revoked access token may be re-i
