## Technical details

A broken access control vulnerability (CWE-862: Missing Authorization) exists in the Slim SEO plugin for WordPress in versions up to and including 4.6.2. The issue stems from insufficient validation of user permissions for certain plugin functions. An authenticated attacker with a minimum of 'Contributor' role privileges can exploit this over the network without user interaction. Successful exploitation allows the attacker to access sensitive information or perform actions typically reserved for higher-privileged users. The vulnerability is resolved in version 4.7.0.
