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.","published":"2026-08-19T17:18:54.073","modified":"2026-08-19T17:18:54.073","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/7f13682cf5f01f69452f723a608ab2d89cfb2133","label":"wazuh/wazuh@7f13682"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/commit/7f13682cf5f01f69452f723a608ab2d89cfb2133"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/pull/36296"},{"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-3v57-hgvj-3vj2"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T17:18:54.073"}}
