CVE-2022-25847Public exploitNetwork attack vector

Browser script execution via unescaped directory filenames

Published Jan 25, 2023 · Updated Apr 1, 2025

Stored XSS in serve-lite before 1.1.2 allows attackers to execute script in a visitor's browser through a crafted filename. The directory-listing loop interpolates each raw filename into an anchor's URL and text without URI encoding or HTML escaping. Exploitation requires a crafted file in the served directory and a user to open its listing, enabling script execution in that site's origin.
