TIMELINE Mar 23 Reserved by GitHub_M Jul 16 EXPLOIT PUBLISHED — CVE-2026-33754 (wazuh). Public exploit reference added. Jul 16 Published (CNA: GitHub_M)
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.9.0 and above, prior to 4.14.5, a remote attacker can trigger memory exhaustion in the cluster protocol parser by sending a crafted message header with an arbitrarily large payload length. The length is trusted before authentication/decryption and used directly to allocate memory, allowing unauthenticated denial of service of the cluster service. This issue has been fixed in version 4.14.5.
