CVE-2026-24095 PUBLISHED

Missing Permission Check on Analyze Configuration Page

Assigner: Checkmk
Reserved: 21.01.2026 Published: 09.02.2026 Updated: 09.02.2026

Improper permission enforcement in Checkmk versions 2.4.0 before 2.4.0p21, 2.3.0 before 2.3.0p43, and 2.2.0 (EOL) allows users with the "Use WATO" permission to access the "Analyze configuration" page by directly navigating to its URL, bypassing the intended "Access analyze configuration" permission check. If these users also have the "Make changes, perform actions" permission, they can perform unauthorized actions such as disabling checks or acknowledging results.
