{"apiVersion":"1.0","identifier":"CVE-2026-74046","description":"Wazuh 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.","publishedAt":"2026-08-18T18:19:34","lastModifiedAt":"2026-08-18T20:17:29","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74046","cvssScore":4.9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00316,"riskScore":0.5,"affectedProduct":"Wazuh","affectedVersions":"<4.14.7","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74046","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74046","en":"https://www.redsauce.net/en/cves/CVE-2026-74046","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74046","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74046","de":"https://www.redsauce.net/de/cves/CVE-2026-74046","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74046","el":"https://www.redsauce.net/el/cves/CVE-2026-74046"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74046"}}
