MuraCMS through 10.1.10 contains a CSRF vulnerability that allows attackers to permanently destroy all deleted content stored in the trash system through a simple CSRF attack. The vulnerable cTrash.empty function lacks CSRF token validation, enabling malicious websites to forge requests that irreversibly delete all trashed content when an authenticated administrator visits a crated webpage. Successful exploitation of the CSRF vulnerability results in potentially catastrophic data loss within the MuraCMS system.

When an authenticated administrator visits a malicious page containing the CSRF exploit, their browser automatically submits a hidden form that permanently empties the entire trash system without any validation, confirmation dialog, or user consent.
