## Technical details

A path traversal vulnerability (CWE-22) exists in the Frappe framework's 'download_backups' functionality. The root cause is a lack of path hardening and sandboxing when handling file requests, allowing an attacker to navigate outside the intended directory. This vulnerability requires high privileges (PR:H) to exploit via a network request. Successful exploitation allows an attacker to read arbitrary files on the server's filesystem that the application process has permissions to access. The fix introduces a 'check_path_safety' utility to ensure requested paths remain within the designated sandbox. Patches are available in versions 15.109.0 and 16.19.0.
