CVE-2026-65931
LimeSurvey Community Edition 7.0.5 - Improper authorization in survey menu entry creation endpoint
Description
LimeSurvey Community Edition 7.0.5 contains an authenticated improper authorization vulnerability in the survey menu entry creation endpoint. An authenticated user with only the global settings:read permission can directly invoke POST /index.php/admin/menuentries/sa/create and create new survey menu entries without the expected settings:update privilege. The endpoint also allows the attacker to submit menu IDs that the normal interface and intended update workflow restrict for non-superadministrators, enabling unauthorized changes to administrative navigation records. This issue affects LimeSurvey: 7.0.5.
