WordPress allows users to generate news pages and web-logs dynamically; it is implemented in PHP with a MySQL database.

The application is prone to an unauthorized-access vulnerability. This issue occurs in the 'xmlrpc.php' script when editing posts. Specifically, the application allows attackers to edit other users' posts without proper authorization.

To exploit this issue, attackers must have authenticated access to the affected application.
