CVE-2026-9802 (GCVE-0-2026-9802)

Title
Keycloak: keycloak: unauthorized account access via replayed refresh tokens after cluster restart
Summary
A flaw was found in Keycloak. When revokeRefreshToken=true is enabled and persistent session storage is in use, a server restart can reset internal timing mechanisms. This allows a remote attacker, who has previously captured a user's refresh token, to replay that token even after it has been revoked. Successful exploitation grants the attacker unauthorized access to the victim's account, potentially leading to information disclosure or privilege escalation.
