Estado: AnalizadaMedia (5.1)—

Perch CMS 3.2 contains a stored cross-site scripting vulnerability that allows authenticated users to upload malicious SVG files with embedded JavaScript. Attackers can craft SVG files with script tags that execute when the file is viewed, potentially stealing user session information or performing client-side attacks.

CVSS
