Technical details
GestSup versions before 3.2.62 fail to properly validate ticket ownership when loading comments via the threadedit parameter in thread.php. An authenticated attacker can enumerate sequential comment IDs to retrieve private comments from other users' tickets without authorization. The vulnerability requires valid authentication but allows horizontal privilege escalation to read arbitrary ticket comments.
