Technical details
The Classified Listing plugin for WordPress (versions 5.4.2 and below) suffers from a broken access control vulnerability due to missing authorization checks (CWE-862). An attacker authenticated with low-level 'Subscriber' privileges can exploit this flaw via network requests to execute functions or modify data that should be restricted to administrative roles. The vulnerability specifically impacts integrity, as indicated by the CVSS vector (I:H). The issue is resolved in version 5.4.3, which introduces proper authorization validation.
