What is CVE-2026-24885?

Kanboard, a project management software that employs the Kanban methodology, contains a vulnerability in the ProjectPermissionController that allows Cross-Site Request Forgery (CSRF) attacks. Before version 1.2.50, the application inadequately enforces the application/json Content-Type for its changeUserRole action. As a result, the server accepts requests with a text/plain Content-Type. An attacker can exploit this oversight to create a malicious web form that, if an authenticated admin user inadvertently accesses it, can lead to unauthorized changes in project user roles. The issue has been addressed in version 1.2.50.

Affected Version(s)
