CVE-2024-24131Public exploitNetwork attack vector

Browser script execution via unfiltered API path

Published Feb 7, 2024 · Updated Jun 5, 2025

Reflected XSS in SuperWebMailer 9.31.0.01799 allows remote attackers to execute script in a user's browser through api.php. The /api/api.php path directly reflects an unfiltered URL-path segment into the response, causing an embedded script element to execute. Exploitation requires a user or administrator to open a crafted URL; the resulting script can access browser data available to the SuperWebMailer origin, including cookies exposed to scripts.
