CVE-2024-12726
📋 TL;DR
The ClipArt WordPress plugin through version 0.2 contains a reflected cross-site scripting (XSS) vulnerability where unsanitized user input is echoed back in pages without proper escaping. This allows attackers to inject malicious scripts that execute in the browser of authenticated users, particularly targeting high-privilege administrators. Any WordPress site using the vulnerable plugin version is affected.

If Mitigated
