{"id":"CVE-2026-25769","summary":"Wazuh Cluster vulnerable to Remote Code Execution via Insecure Deserialization","details":"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.","aliases":["GHSA-3gm7-962f-fxw5"],"modified":"2026-04-10T05:40:46.629640Z","published":"2026-03-17T17:41:08.640Z","database_specific":{"cwe_ids":["CWE-502"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25769.json"},"references":[{"type":"WEB","url":"https://drive.google.com/drive/folders/1WlkKNmHexz8212OVED9O6M_3pI8b6qNI?usp=sharing"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25769.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-3gm7-962f-fxw5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25769"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"8c2c62a6e9dcbcf2c792f7924e8cfdb26842820b"},{"fixed":"b6b6e94a432f7a3e20d1eea1c58ebd01d2d30999"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25769.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
