CVE-2024-4530
📋 TL;DR
The Business Card WordPress plugin through version 1.0.0 lacks Cross-Site Request Forgery (CSRF) protection on certain endpoints, allowing attackers to trick authenticated users into performing unauthorized actions like editing card categories. This affects WordPress sites running the vulnerable plugin version. Attackers can exploit this when users with appropriate privileges visit malicious pages while logged in.
