This vulnerability could allow a remote authenticated user to move or access files belonging to other users on the same device. The vulnerability stems from a failure to properly validate file paths, potentially leading to path traversal. This issue allows an attacker with valid credentials to elevate their privileges and access sensitive information stored on the device outside of their designated file paths.
