## What is CVE-2026-65931?

CVE-2026-65931 is a medium-severity missing authorization vulnerability in LimeSurvey, published on 27 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official 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.

Weakness: CWE-862 (Missing Authorization)
