{"apiVersion":"1.0","identifier":"CVE-2026-49441","description":"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.","publishedAt":"2026-08-19T17:18:54","lastModifiedAt":"2026-08-19T19:17:17","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-49441","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00461,"riskScore":0.95,"affectedProduct":"Wazuh","affectedVersions":">=4.3.0,<4.14.6,==5.0.0-beta3","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-49441","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-49441","en":"https://www.redsauce.net/en/cves/CVE-2026-49441","fr":"https://www.redsauce.net/fr/cves/CVE-2026-49441","pt":"https://www.redsauce.net/pt/cves/CVE-2026-49441","de":"https://www.redsauce.net/de/cves/CVE-2026-49441","sk":"https://www.redsauce.net/sk/cves/CVE-2026-49441","el":"https://www.redsauce.net/el/cves/CVE-2026-49441"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-49441"}}
