How to fix

Fixed in: ZoneMinder 1.36.63

Technical details

The validateToken() function in web/includes/auth.php returns false on invalid or malformed tokens, but the caller assigns this boolean value to the global $user variable. Because isset($user) evaluates to true even when $user is boolean false, the authentication gate in web/index.php (which checks !isset($user)) is bypassed. This allows unauthenticated requests with a malformed ?token parameter to reach views like the zones display, which leaks monitor and zone metadata without permission checks. Privilege-sensitive operations correctly deny the false user value, preventing unauthorized state changes.
