CVE-2025-47817Network attack vector

Authenticated privilege escalation via editable role parameter

Published May 10, 2025 · Updated May 12, 2025

Privilege escalation in BlueWave Labs Checkmate 2.0.2 and earlier allows remote authenticated users to grant themselves elevated roles. The editUserBodyValidation schema in server/validation/joi.js accepts a client-controlled role array in profile edit requests, and the update flow applies that field to the requesting account. Any signed-in low-privilege account can therefore obtain administrative permissions and exercise administrator-only control over the application.
