Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Vvveb CMS due to insufficient authentication and input sanitization in the visual editor's preview functionality. The 'isEditor()' function in 'system/functions.php' incorrectly validates editor status based solely on the presence of the 'r' query parameter without verifying sessions or roles. Consequently, the view handler in 'system/core/view.php' accepts raw HTML from the 'html' POST parameter and injects it directly into the response body when '_component_ajax' is present. An unauthenticated attacker can exploit this by crafting a malicious link or auto-submitting form to execute arbitrary JavaScript in a victim's browser. This vulnerability was patched in version 1.0.8.2 by adding proper admin and user key checks.
