CVE-2024-33724Public exploitNetwork attack vector

Session compromise via reflected groupe_id script injection

Published May 8, 2026 · Updated May 8, 2026

Reflected XSS in SOPlanning 1.52.00 allows remote attackers to execute script in a user's browser via a crafted groupe_id request. The process/groupe_save.php handler reflects groupe_id without neutralizing a quote-and-script payload, allowing it to escape its output context. A user must follow the crafted URL while authenticated; the script then runs under the SOPlanning origin and can expose that user's session or act with the user's privileges.
