Technical details

A path traversal vulnerability (CWE-22) exists in Rejetto HFS versions 3.0.0 through 3.2.0 within the 'lang' query parameter. A remote, unauthenticated attacker can exploit this by submitting specially crafted requests to access files outside of the designated shared directories. The exploit is constrained by the application's logic to only retrieve files that match a specific JSON naming and format pattern, which limits the scope of the data disclosure. The issue is resolved in version 3.2.1.
