CVE-2025-64094Network attack vector

Stored XSS via incomplete SVG script filtering

Published Oct 28, 2025 · Updated Oct 28, 2025

Stored XSS in DNN Platform before 10.1.1 allows remote authenticated users to execute JavaScript through uploaded SVG files. The SVG content sanitizer incompletely detects script elements, allowing a crafted file to retain executable code after validation. A low-privileged account with file-upload access is sufficient, and the code runs in a visitor's browser in the site's origin, enabling session hijacking, data exfiltration, or page defacement.
