Summary

WSO2 API Manager, WSO2 Traffic Manager, WSO2 Universal Gateway, WSO2 API Control Plane, WSO2 Identity Server and other products are affected when allowed_scopes is enabled. Token introspection keeps a cached token after a revocation request (CWE-613). A revoked token may be re-issued until the cache is cleared, and affected users may be unable to obtain a valid token, which disrupts authentication flows.

Written with Claude Haiku 5.5 from the sources below · 2026-11-05

Description from the CNA

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-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.
