Project role escalation via forged plaintext request
Published Feb 10, 2026 · Updated Feb 10, 2026
CSRF in Kanboard before 1.2.50 allows remote authenticated users to change project roles by inducing an administrator’s browser to submit a request. The changeUserRole action in ProjectPermissionController performs no CSRF validation and accepts text/plain bodies instead of requiring application/json. Exploitation requires a low-privileged account and an authenticated administrator to load attacker-controlled content, after which the attacker can elevate a project role.
