Detailed vulnerability description
The vulnerability allows a remote user to continue using a logged-out session to perform API requests.
The vulnerability exists due to insufficient session expiration in the session handling logic of multi-node Graylog clusters when processing API requests with the X-Graylog-No-Session-Extension:true header after logout. A remote user can send crafted API requests using a previously valid session identifier to continue using a logged-out session to perform API requests.
Only multi-node cluster deployments are affected, and the session remains usable until its original timeout expires.
