Technical details

The generic JSON decoder in wazuh-analysisd fails to properly release memory when processing events containing duplicate fields (such as repeated 'id' fields), leading to a memory leak. An attacker can enroll an agent through passwordless enrollment and trigger the leak by sending specially crafted JSON events, eventually causing an OOM kill of the analysisd process and disabling security alerts.
