Kanboard · Kanboard · CVE-2026-29056
**Name of the Vulnerable Software and Affected Versions**
Kanboard versions prior to 1.2.51
**Description**
Kanboard is project management software focused on the Kanban methodology. The user invite registration endpoint (`UserInviteController::register()`) accepts all POST parameters and passes them to `UserModel::create()` without filtering the `role` field. An attacker receiving an invite link can inject `role=app-admin` into the registration form to create an administrator account. The `role` parameter is vulnerable to injection.
**Recommendations**
Versions prior to 1.2.51 should be updated to version 1.2.51 or later.
