Vulnerability from github – Published: 2019-06-13 20:38 – Updated: 2021-08-16 15:25

Summary

Forced Logout in keycloak-connect

Details

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.

Severity ?

5.5 (Medium)
