  - Cockpit CMS before release 364 contains a path traversal and local file inclusion vulnerability that
    allows unauthenticated attackers to read arbitrary files or execute PHP files by including unvalidated
    PATH_INFO derived from REQUEST_URI in filesystem path construction without containment checks. Attackers
    can inject dot-dot sequences into the URL to traverse outside the designated spaces directory, and when
    the resolved path ends with a .php extension, the application passes it to include(), enabling local file
    inclusion on deployments using the PHP built-in server or certain non-default Nginx configurations.
