Strategy11 vulnerabilities and threats

Formidable Charts plugin for WordPress up to version 2.0.1 is vulnerable to a directory traversal flaw via the 'frm_graph' parameter. This vulnerability allows unauthenticated attackers to read arbitrary files on the server if certain conditions are met, including having Formidable Forms Lite, Pro, and Charts active and the existence of the wp-content/uploads/frm-charts/ directory. The vulnerability has a high severity rating with a CVSS score of 7.5.

The Formidable Digital Signatures plugin for WordPress is vulnerable to file deletion due to insufficient file path validation in the delete_file function in all versions up to, and including, 3.0.6. This makes it possible for unauthenticated attackers to delete files on the server by supplying an attacker-controlled filename in the item_meta[field_id][content] parameter alongside the delete_saved_image flag during the standard entry-creation POST flow on any form that accepts anonymous submissions.
