CyberRota Analysis

AI-Generated

The Kimai time tracking application prior to version 2.57.0 is vulnerable due to improper access controls on the GET /api/timesheets list endpoint, allowing users with the view_other_timesheet permission to access sensitive data of other users without proper verification. This could lead to unauthorized disclosure of timesheet details, including descriptions, timing data, and rates. Organizations using affected versions should prioritize this update to protect user privacy and maintain data integrity.

Original NVD Description

Kimai is an open-source time tracking application. Prior to 2.57.0, the GET /api/timesheets list endpoint accepts user and users[] target identifiers from a caller with view_other_timesheet but does not apply access_user or verify that a ROLE_TEAMLEAD requester leads a team containing each target user. TimesheetController::cgetAction() adds the resolved users directly to the query while project and customer filtering still permits records on unscoped projects or projects sharing ordinary team membership, allowing a teamlead to retrieve another user's descriptions, timing data, tags, rate, and internalRate even though GET /api/timesheets/{id} would deny access through TimesheetVoter. This issue is fixed in version 2.57.0.
