CVE-2024-22720Public exploitNetwork attack vector

Stored HTML injection via unescaped group names

Published Jan 24, 2024 · Updated Jun 5, 2025

Stored cross-site scripting in Kanboard 1.2.34 allows remote authenticated users to inject HTML into another user's profile page. The group-membership view renders a user-controlled group name without HTML escaping when it displays memberships on the user profile. An administrator-level attacker must create or rename a group and induce another user to view the affected profile, allowing attacker-supplied markup to alter content in that user's browser.
