Technical details

A directory traversal vulnerability exists in the Ninja Forms - Excel Export plugin for WordPress due to insufficient validation of the 'spreadsheet_export_tmp_name' parameter. The flaw is located within the file handling logic, specifically affecting components like ExtractPostData.php and ExportFile.php. An authenticated attacker with at least subscriber-level privileges can manipulate this parameter to perform path traversal, allowing them to write .xls or .xlsx files to arbitrary directories on the server. While the impact is limited to file creation (integrity), it can be leveraged to stage further attacks or disrupt server organization. The vulnerability affects all versions up to and including 3.3.6.
