cve-program · CVE-2026-74046
PublishedWazuh 4.4.0 before 4.14.7 contains a denial of service vulnerability in the fdecompress_files() function within cluster.py that allows authenticated cluster peers to exhaust memory by supplying a malicious synchronization archive without decompressed size limits. Attackers holding a valid cluster Fernet key can upload a small, highly compressed zip bomb archive that forces wazuh-clusterd on the master node to decompress the full payload into memory, causing memory exhaustion and service disruption.
