Active Record Tenanted versions prior to 0.7.0 contain a vulnerability in the override of Active Storage's DiskService#path_for method. This vulnerability allows path traversal by not validating that the resolved filesystem path remains within the storage root directory. If an attacker can supply a blob key with path traversal sequences, they could potentially read, write, or delete arbitrary files on the server. The issue arises when untrusted user input is used as blob keys, which are expected to be trusted strings. The vulnerability has a low severity rating and no known exploits in the wild. Upgrading to version 0.7.0 or later mitigates the issue.
