{"id":"CVE-2026-25769","state":"PUBLISHED","title":"Wazuh Cluster vulnerable to Remote Code Execution via Insecure Deserialization","description":"Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.0.0 through 4.14.2 have a Remote Code Execution (RCE) vulnerability due to Deserialization of Untrusted Data). All Wazuh deployments using cluster mode (master/worker architecture) and any organization with a compromised worker node (e.g., through initial access, insider threat, or supply chain attack) are impacted. An attacker who gains access to a worker node (through any means) can achieve full RCE on the master node with root privileges. Version 4.14.3 fixes the issue.","publishedAt":"2026-03-17T17:41:08.640Z","updatedAt":"2026-03-18T03:55:49.623Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["wazuh wazuh"],"affected":[{"vendor":"wazuh","product":"wazuh","versions":[{"version":">= 4.0.0, < 4.14.3","status":"affected"}]}],"references":["https://github.com/wazuh/wazuh/security/advisories/GHSA-3gm7-962f-fxw5","https://drive.google.com/drive/folders/1WlkKNmHexz8212OVED9O6M_3pI8b6qNI?usp=sharing"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/25xxx/CVE-2026-25769.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-25769","state":"PUBLISHED","datePublished":"2026-03-17T17:41:08.640Z","dateUpdated":"2026-03-18T03:55:49.623Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-05T18:35:52.359Z"},"containers":{"cna":{"title":"Wazuh Cluster vulnerable to Remote Code Execution via Insecure Deserialization","descriptions":[{"lang":"en","value":"Wazuh is a free and open source platform used for threat prevention, detection, and response.
