CVE-2026-52828 Details
Description
Kimai is an open-source time tracking application. Prior to 2.58.0, ExportController::createExportTemplate() and ExportController::editExportTemplate() inherit only the class-level create_export permission, which ROLE_TEAMLEAD receives by default, and omit the create_export_template permission required by the API routes and user interface. A teamlead can directly access the export template creation and editing web routes to create or modify global ExportTemplate records marked available to all users, altering export columns, renderer, format, and output used by other users and administrators. This issue is fixed in version 2.58.0.
A vulnerability in Kimai's ExportController allows users with the ROLE_TEAMLEAD to create and edit global export templates via web routes, bypassing the intended permission requirements. This issue affects Kimai versions through 2.57.0. The vulnerability arises because the web routes only check for the broader 'create_export' permission, which is granted to team leads, instead of the stricter 'create_export_template' permission reserved for administrators. As a result, a team lead can modify export templates that impact all users, including admins.
Users should update to Kimai version 2.58.0 or newer, where this vulnerability has been patched.
