Name of the Vulnerable Software and Affected Versions QuickCMS versions prior to 6.8 patch 15.05.2026

Description QuickCMS allows a user session identifier to be established before authentication, and this value remains unchanged after the user authenticates. This behavior enables session fixation, where an attacker can predetermine a session ID for a victim and subsequently hijack the session once the victim has authenticated.

Recommendations Apply the patch published on 15.05.2026 for version 6.8.
