The vendor provides a patch which should be installed immediately. Specific fixed version information was not provided. Affected parties should contact the vendor to request the update.

Restrict branch-management privileges to trusted administrative users only. Validate branch codes on the server side using a strict allowlist of safe characters and reject path separators, traversal sequences, control characters, and other special characters. Ensure that filesystem paths are canonicalized and checked against an expected base directory before file operations are performed. Review service-account filesystem permissions so that the application can only write to required storage locations. These measures should only be treated as interim risk reduction; the vendor-provided patch should be installed.
