Cameleon CMS Persistent Cross-Site Scripting Vulnerability

Vulnerability

A persistent cross-site scripting vulnerability has been identified in Cameleon CMS version 2.7.4. This vulnerability allows authenticated administrators to inject malicious scripts into post titles. The injected scripts can execute when other users hover over the post title, potentially leading to the theft of session cookies and the execution of arbitrary JavaScript.

Impact
