CVE-2024-13140Public exploitNetwork attack vector

Stored XSS via unfiltered SVG cover upload

Published Jan 5, 2025 · Updated Jan 6, 2025

Stored XSS in emlog Pro 2.4.0 through 2.4.3 allows remote authenticated users to execute script in visitors' browsers via cover uploads. The /admin/article.php?action=upload_cover handler accepts an SVG from the image field without filtering embedded XML animation handlers. Content-editing permission is required; rendering the stored SVG triggers attacker-controlled JavaScript in the site origin.
