CyberRota Analysis

AI-Generated

The Kimai time tracking application prior to version 2.57.0 is vulnerable due to insufficient access control on the creation of activities and projects, allowing users to create child objects under unauthorized parent projects or customers. This can lead to configuration pollution, potentially affecting time-entry, billing, and reporting accuracy. Organizations using Kimai for project management and time tracking should prioritize upgrading to version 2.57.0 to mitigate these risks.

Original NVD Description

Kimai is an open-source time tracking application. Prior to 2.57.0, GET or POST requests to /en/admin/activity/create/{project} and /en/admin/project/create/{customer} require only the generic create_activity or create_project capability and do not verify edit access to the supplied Project or Customer object. A user who knows a valid project.id or customer identifier can use the preset-parent creation logic in src/Controller/ActivityController.php or src/Controller/ProjectController.php to persist a new child business object under an unauthorized parent, polluting project or customer configuration and influencing later time-entry, rate, reporting, and billing behavior. This issue is fixed in version 2.57.0.
