CVE-2023-4910

Token disclosure via cached post-logout page

Published Nov 6, 2023 · Updated Nov 20, 2025

Sensitive-data exposure in Red Hat 3scale API Management allows local users to view personal access tokens after account logout. The Admin Portal's personal tokens response remains renderable from the browser's history cache after logout instead of being invalidated or marked non-cacheable. Exploitation requires prior authenticated access to the personal tokens page and subsequent local access to the same browser profile; the reported consequence is disclosure of displayed tokens.
