Description
Wazuh Manager from 3.0.0 before 4.14.9 contains a memory leak vulnerability in the generic JSON decoder that allows remote attackers to exhaust wazuh-analysisd memory via repeated static fields. Attackers can enroll an agent through passwordless enrollment and send events with duplicate fields such as id, triggering an OOM kill that disables alerting.
