CVE-2026-84155

Session Token Remains Valid After Logout in Multi-Worker Deployments

Published Nov 6, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
CodeChecker's web server fails to fully invalidate a session token on logout when the server runs with more than one API worker process (the default). Each worker process maintains its own
in-memory session cache; logout only clears the cache of the single worker that handles the request (plus the shared database record). Other workers continue to honor the destroyed token
from their stale in-memory copies until the session's lifetime expires. An attacker who has captured a valid token can therefore keep impersonating the user after the user has logged out.
