{"id":"CVE-2026-44901","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-44901","summary":"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.","published":"2026-08-19T17:18:49.283","modified":"2026-08-19T17:18:49.283","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/wazuh/wazuh/commit/b29849f8abb08d78f257e6106b6111a8a1b0e621","label":"wazuh/wazuh@b29849f"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/commit/b29849f8abb08d78f257e6106b6111a8a1b0e621"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/pull/35757"},{"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":"WEB","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-8c6v-7g3w-prrq"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T17:18:49.283"}}
