Medium 6.3

A medium-severity cross-site request forgery in kimai from kimai. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 13% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
