CVE-2026-40349: Leepeuker Movary

High severity, CVSS 8.8. EPSS: 0.6% chance of exploitation in the next 30 days.

Movary is a self hosted web app to track and rate a user's watched movies. Prior to version 0.71.1, an ordinary authenticated user can escalate their own account to administrator by sending `isAdmin=true` to `PUT /settings/users/{userId}` for their own user ID. The endpoint is intended to let a user edit their own profile, but it updates the sensitive `isAdmin` field without any admin-only authorization check. Version 0.71.1 patches the issue.

Affected products

• Leepeuker Movary: before 0.71.1 (fixed in 0.71.1)
