CVE-2026-65931Network attack vectorHinoki check available

Unauthorized menu entry creation via missing permission check

Published Aug 27, 2026 · Updated Aug 27, 2026

Improper authorization in LimeSurvey 7.0.5 allows remote authenticated users to create survey menu entries through an admin endpoint. The POST /index.php/admin/menuentries/sa/create handler accepts requests from accounts holding only settings:read and omits the expected settings:update authorization check. Such access is sufficient to use menu IDs normally restricted to superadministrators, enabling unauthorized changes to administrative navigation records.
