## Technical details

The vulnerability is a path traversal (CWE-22) in the /filemanager/controller compress method. The application validates only domain ownership but fails to canonicalize or restrict file paths supplied in the request, allowing attacker-controlled paths to be concatenated into zip or tar commands executed as the web process user. An authenticated attacker with site-level privileges (no admin required) can read any file accessible to the panel process.
