Short explanation

CVE-2026-84808 reveals an authorization bypass in Kimai before 2.65.0, allowing unauthorized access to team-restricted timesheet data via API. No confirmed patch exists. Vulnerability is rated MEDIUM with CVSS 5.3.

Why does it matter?

Unauthorized access to team-specific time records could lead to data breaches. The vulnerability affects only specific user roles and endpoints, but impacts data privacy in time-tracking systems. No active exploitation or ransomware use is reported.

What should be done?

  • Upgrade to Kimai 2.65.0 or later to resolve the vulnerability.
  • Verify vendor advisories for official patch details.
  • Do not use versions below 2.65.0 without mitigation.

Show the technical text from the sources

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.
