CVE-2024-2376
📋 TL;DR
The WPQA Builder WordPress plugin before version 6.1.1 lacks Cross-Site Request Forgery (CSRF) protection on certain endpoints, allowing attackers to trick authenticated users into performing unintended actions. This affects all WordPress sites using vulnerable versions of the WPQA Builder plugin. Attackers could exploit this to modify settings, delete content, or perform other administrative actions without the user's consent.
