CVE-2024-9544Network attack vector

Stored cross-site scripting via unsafe SVG file uploads

Published May 22, 2025 · Updated Apr 8, 2026

Stored cross-site scripting in MapSVG 8.6.4 and earlier allows remote authenticated users to inject scripts through SVG file uploads. The plugin accepts uploaded SVG content without sufficient input sanitization and serves it without adequate output escaping, leaving embedded web script executable. Contributor-level access or higher is required, and the payload runs when a user accesses the uploaded SVG file.
