    "title": "LimeSurvey Community Edition 7.0.5 - Improper authorization in survey menu entry creation endpoint",
    "summary": "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.",
