AI Analysis
Technical Summary
CVE-2026-15227 describes a missing authorization vulnerability in Checkmk monitoring software where authenticated users lacking the specific permission to edit reports owned by other users can still modify those reports. The affected versions include all releases before 2.5.0p10, 2.4.0p35, 2.3.0p49, and the unsupported 2.2.0 version. This vulnerability is categorized under CWE-862 (Missing Authorization). There is no evidence of known exploits in the wild, and no patch or official remediation information is provided in the available data.
Potential Impact
An authenticated user without the proper 'Edit foreign Reports' permission can modify reports owned by other users, potentially leading to unauthorized changes in monitoring data or report content. This could affect data integrity and trustworthiness of reports within the Checkmk environment. The severity is assessed as medium/moderate.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user permissions carefully to minimize exposure. Monitor vendor channels for updates and apply patches promptly when released.
