CVE-2025-4647Network attack vector

Authenticated browser script execution via SVG replacement

Published May 13, 2025 · Updated May 13, 2025

Reflected XSS in affected Centreon Web releases allows remote authenticated users to execute script through crafted SVG media. The media-upload component permits replacement content for an existing SVG to bypass its sanitization measures, causing a browser to render attacker-controlled script. Elevated privileges are required to replace the SVG, and another user must view it; the script runs in that user's browser context.
