From 4.3.0 until 4.14.6 and 5.0.0-beta3, the non-merged branch of process_files_from_worker() in framework/wazuh/core/cluster/master.py trusts a peer-controlled file_path key from files_metadata.json. The destination is joined to WAZUH_PATH without proving that it remains inside the directory selected by cluster_item_key. A cluster peer holding the shared Fernet key can upload a crafted extra-valid archive and overwrite security-sensitive files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution after a service reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3."}], "lastModified": "2026-09-15T19:21:34.670", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:wazuh:wazuh:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5683CDC8-5658-4FB0-A0FA-326832F00691", "versionEndExcluding": "4.14.6", "versionStartIncluding": "4.3.0"}, {"criteria": "cpe:2.3:a:wazuh:wazuh:5.0.0:beta1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "007B01AA-AED0-4E92-8999-07E74B630460"}, {"criteria": "cpe:2.3:a:wazuh:wazuh:5.0.0:beta2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "2CA11D49-6706-4ADE-A639-7034B630B96A"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
