Summary Forced Logout in keycloak-connect Versions of `keycloak-connect` prior to 4.4.0 are vulnerable to Forced Logout. The package fails to validate JWT signatures on the `/k_logout` route, allowing attackers to logout users and craft malicious JWTs with NBF values that prevent user access indefinitely. ## Recommendation Upgrade to version 4.4.0 or later.
