CVE-2026-49992

Kimai: Login CSRF in Default Team Creation Endpoints Allows Unauthorized Team and Permission Structure Changes

Published Sep 11, 2026 CVSS 4.0 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
Kimai is an open-source time tracking application. Versions prior to 2.58.0 contain authenticated cross-site request forgery issues in their default team creation shortcuts for projects, customers, and activities. These endpoints are exposed through `GET` routes and directly create or reuse a `Team`, add the current user as teamlead, and bind the target object to that team. As a result, an attacker can trick a logged-in user with the required permissions into visiting a malicious page and cause unauthorized changes to team, teamlead, and object-binding relationships. This is a real authorization-structure modification issue rather than a harmless UI shortcut. Version 2.58.0 patches the issue.
