{"apiVersion":"1.0","identifier":"CVE-2026-44901","description":"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-beta2, AffectedItemsWazuhResult.merge() in framework/wazuh/core/results.py trusts the sort_casting field in a cluster worker-s JSON response. During a distributed API merge, attacker-controlled type names are resolved through Python builtins without an allowlist. A compromised worker can set sort_casting to exec and place Python source in affected_items, causing the master to execute the payload as root when responses from multiple nodes are merged. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.","publishedAt":"2026-08-19T17:18:49","lastModifiedAt":"2026-08-19T18:16:39","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44901","cvssScore":8.4,"cvssVector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00412,"riskScore":0.87,"affectedProduct":"Wazuh","affectedVersions":">=4.0.0,<4.14.6,==5.0.0-beta2","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-44901","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-44901","en":"https://www.redsauce.net/en/cves/CVE-2026-44901","fr":"https://www.redsauce.net/fr/cves/CVE-2026-44901","pt":"https://www.redsauce.net/pt/cves/CVE-2026-44901","de":"https://www.redsauce.net/de/cves/CVE-2026-44901","sk":"https://www.redsauce.net/sk/cves/CVE-2026-44901","el":"https://www.redsauce.net/el/cves/CVE-2026-44901"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-44901"}}
