Sources and claim methodology

  • Source referencevulncheck.com
Upstream source description

Kimai versions before 2.65.0 contain an authorization bypass vulnerability in the REST API timesheet collection endpoint that fails to enforce activity-team access controls. Users with view_other_timesheet permission can list timesheets using activities restricted to teams they do not belong to, bypassing intended data isolation.
