Kanboard Affected by Cross-Site Request Forgery (CSRF) via Content-Type Misconfiguration in Project Role Assignment
Source: CVE Program / CVE List V5
Vulnerability Description
Kanboard is project management software focused on Kanban methodology. Prior to 1.2.50, a Cross-Site Request Forgery (CSRF) vulnerability exists in the ProjectPermissionController within the Kanboard application. The application fails to strictly enforce the application/json Content-Type for the changeUserRole action.

Which allows unauthorized modification of project user roles if an authenticated admin visits a malicious site This vulnerability is fixed in 1.2.50.
