CVE-2026-80202 Details

UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

Kimai before 2.56.0 does not enforce team-membership checks in TimesheetVoter::voteOnAttribute(), which maps permissions only to own_timesheet or other_timesheet. As a result, any authenticated user with ROLE_TEAMLEAD (or a role holding edit_other_timesheet/delete_other_timesheet) can read, modify, and permanently delete timesheets belonging to any user system-wide via the API, regardless of team membership. Timesheet IDs are sequential integers and trivially enumerable. ROLE_USER accounts are correctly restricted. (Note: the maintainers characterize this behavior as matching the documented permission model.)
