CVE-2023-43326Public exploitNetwork attack vector

Session impersonation via unescaped route-path reflection

Published Sep 25, 2023 · Updated Sep 24, 2024

Reflected XSS in multiple mooSocial 3.1.8 routes allows remote attackers to steal session cookies through a crafted URL. The public proof of concept shows route paths reflecting an appended img element and onerror handler into HTML without neutralization. A victim must open the crafted URL; the script then runs under the site's origin and can expose the session cookie for account impersonation.
