Technical details
The plugin uses an administrator-controlled backup storage directory path without proper validation before creating directories and writing files, enabling path traversal attacks (CWE-22). An authenticated administrator can specify a directory path containing traversal sequences (e.g., `../../../`) to place backup files outside the intended location. A fix is available in version 0.9.138 and later.
