Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site request forgery (CVE-ID: CVE-2026-24885)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: 6.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a low-privileged remote attacker to escalate their Kanboard project role from Project Viewer to Project Manager.

The vulnerability exists due to missing CSRF validation and acceptance of text/plain requests containing JSON in the ProjectPermissionController changeUserRole action. A low-privileged remote attacker can induce an authenticated administrator to visit a malicious site that submits a forged role assignment request using the administrator’s session.
