{"id":"CVE-2026-48024","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-48024","summary":"Wazuh is a free and open source platform used for threat prevention, detection, and response.

From 4.0.0 until 4.14.6 and 5.0.0-beta3, cluster.unmerge_info() in framework/wazuh/core/cluster/cluster.py constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. process_files_from_worker() in framework/wazuh/core/cluster/master.py does not adequately confine the resulting path to the declared cluster item directory. A cluster peer holding the shared Fernet key can use traversal in files_metadata.json or a merged-file header to write files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution when Wazuh services reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.","published":"2026-08-19T17:18:51.093","modified":"2026-08-19T17:18:51.093","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/wazuh/wazuh/commit/88fc89fdfb1bf37b9d826e9c281a3d22655733de","label":"wazuh/wazuh@88fc89f"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/commit/88fc89fdfb1bf37b9d826e9c281a3d22655733de"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/pull/36204"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/releases/tag/v4.14.6"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/releases/tag/v5.0.0-beta3"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-gh4h-fx78-q8xc"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T17:18:51.093"}}
