Name of the Vulnerable Software and Affected Versions Rejetto HFS versions 3.0.0 through 3.2.0

Description An issue exists that allows a remote unauthenticated attacker to perform path traversal via the lang query parameter. This enables the reading of specific JSON files located outside the shared folders. The impact is limited because exploitation is restricted to files that follow a specific naming and format pattern.
