Description
CVE-2026-112336 is a memory leak vulnerability in Wazuh Manager versions 3.0.0 up to but not including 4.14.9. The flaw exists in the generic JSON decoder, where repeated static fields in events can cause memory exhaustion. An attacker can exploit this by enrolling an agent without a password and sending events with duplicate fields such as 'id', leading to an out-of-memory (OOM) kill that disables alerting functionality.
