CVE-2022-50905Public exploitNetwork attack vectorHinoki check available

Script execution via unescaped URL or SVG upload

Published Jan 13, 2026 · Updated Jan 13, 2026

Cross-site scripting in e107 CMS 3.2.1 allows remote authenticated users to execute script in other users' browsers via comments or SVG uploads. news.php inserts a crafted path segment into the comment form's action attribute without neutralizing attribute-breaking characters, while image.php accepts remotely fetched SVG content as an image. The reflected path requires an authenticated commenter and subsequent field interaction; the stored path requires an administrator to import an SVG and a user to access it.
