{"id":"CVE-2026-49441","summary":"Wazuh : peer-controlled metadata key in process_files_from_worker non-merged branch allows arbitrary file write under WAZUH_PATH on Wazuh manager","details":"Wazuh is a free and open source platform used for threat prevention, detection, and response. 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.","aliases":["GHSA-3v57-hgvj-3vj2"],"modified":"2026-10-28T02:30:45.009513846Z","published":"2026-08-19T16:19:37.206Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49441.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-73"]},"references":[{"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":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49441.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-3v57-hgvj-3vj2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49441"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/commit/7f13682cf5f01f69452f723a608ab2d89cfb2133"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/pull/36296"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"5bae1c1830dbf11acc8a06e01f7a5a134b767760"},{"fixed":"44c2925b46bd058d2426bd44ed1b3e5d7b7b03b4"},{"introduced":"cddd833300cb5af494ba7dab31192bae649eb184"},{"fixed":"7f13682cf5f01f69452f723a608ab2d89cfb2133"},{"fixed":"da844a6fdafd7388d11114841482596d1efdf5b3"}],"database_specific":{"extracted_events":[{"source":"CPE_RANGE","cpe":"cpe:2.3:a:wazuh:wazuh:*:*:*:*:*:*:*:*","range":[{"introduced":"4.3.0"},{"fixed":"4.14.6"}]},{"cpe":"cpe:2.3:a:wazuh:wazuh:5.0.0:beta1:*:*:*:*:*:*","range":[{"introduced":"5.0.0-beta1"},{"last_affected":"5.0.0-beta1"}],"source":"CPE_STRING"},{"source":"CPE_STRING","cpe":"cpe:2.3:a:wazuh:wazuh:5.0.0:beta2:*:*:*:*:*:*","range":[{"introduced":"5.0.0-beta2"},{"last_affected":"5.0.0-beta2"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"7f13682cf5f01f69452f723a608ab2d89cfb2133"}]},{"range":[{"fixed":"44c2925b46bd058d2426bd44ed1b3e5d7b7b03b4"}],"source":"REFERENCES_TAG","original_tag":"v4.14.6"},{"original_tag":"v5.0.0-beta3","range":[{"fixed":"da844a6fdafd7388d11114841482596d1efdf5b3"}],"source":"REFERENCES_TAG"}]}}],"versions":["5.0.0-beta1","5.0.0-beta2","v5.0.0-beta2","v5.0.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49441.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
