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.
