description

OpenSave versions through 2.4.0 do not adequately constrain save locations supplied by paired peers. A paired attacker may access files outside the configured save directories, including by causing file reads or writes.

mitigation

Allow pairing only with trusted peers and restrict access to the sync service at the network layer. Run OpenSave with filesystem permissions limited to its intended save directories while awaiting a vendor-provided fixed release.
