CVE-2026-84808Network attack vectorHinoki check available

Restricted timesheet disclosure via missing activity-team filter

Published Sep 2, 2026 · Updated Sep 2, 2026

Authorization bypass in Kimai before 2.65.0 allows remote authenticated users to read restricted timesheet metadata through its REST API. TimesheetRepository::addPermissionCriteria() filters customer and project teams but omits the activity-team constraint when building collection queries. A caller needs view_other_timesheet permission, and the installation must use team-restricted activities; records cannot be created, changed, or deleted.
