# CVE-2026-96460: Keycloak-services: keycloak-services: indefinite access token renewal via standard token exchange v2

Status: published. Published: 2026-11-06. Updated: 2026-11-06.

A flaw was found in the token exchange mechanism of Keycloak. When using Standard Token Exchange V2, the system issues new tokens with a fresh lifetime based on the requester clients configuration instead of limiting it to the original tokens expiration. This issue allows an authenticated requester to indefinitely extend access for service accounts by repeatedly exchanging tokens, even if the original client has been disabled by an administrator.
