{"id":"CVE-2026-44901","summary":"Wazuh Cluster DAPI Protocol Deserialization of Untrusted Data Remote Code Execution Vulnerability","details":"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.","aliases":["GHSA-8c6v-7g3w-prrq"],"modified":"2026-09-17T03:46:42.664073737Z","published":"2026-08-19T16:12:12.305Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-502"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44901.json"},"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-beta2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44901.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-8c6v-7g3w-prrq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44901"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/commit/b29849f8abb08d78f257e6106b6111a8a1b0e621"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/pull/35757"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"8c2c62a6e9dcbcf2c792f7924e8cfdb26842820b"},{"fixed":"44c2925b46bd058d2426bd44ed1b3e5d7b7b03b4"},{"introduced":"cddd833300cb5af494ba7dab31192bae649eb184"},{"fixed":"b29849f8abb08d78f257e6106b6111a8a1b0e621"},{"fixed":"b58b3b2552497639b1b2a2b23e8de87e4ce9cf02"}],"database_specific":{"source":["CPE_RANGE","CPE_STRING","REFERENCES"],"cpe":["cpe:2.3:a:wazuh:wazuh:*:*:*:*:*:*:*:*","cpe:2.3:a:wazuh:wazuh:5.0.0:beta1:*:*:*:*:*:*","cpe:2.3:a:wazuh:wazuh:5.0.0:beta2:*:*:*:*:*:*"],"extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.14.6"},{"introduced":"5.0.0-beta1"},{"last_affected":"5.0.0-beta1"},{"introduced":"5.0.0-beta2"},{"last_affected":"5.0.0-beta2"}]}}],"versions":["5.0.0-beta1","5.0.0-beta2","v5.0.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44901.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
