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.\n\n## Affected\n\n- `wazuh >= 4.0.0, < 4.14.6`\n- `wazuh = 5.0.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `wazuh 4.14.6`","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":46.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
