{"apiVersion":"1.0","identifier":"CVE-2026-74039","description":"Wazuh 4.0.0 before 4.14.7 and 5.0.0-beta2 contain a denial of service vulnerability that allows authenticated attackers with allow_run_as enabled to exhaust CPU resources by submitting arbitrarily deeply nested JSON structures to the POST /security/user/authenticate/run_as endpoint. Attackers can repeatedly submit malformed auth_context bodies with unlimited nesting depth to cause the API framework to consume excessive CPU, denying service to all other API consumers.","publishedAt":"2026-08-18T18:19:33","lastModifiedAt":"2026-08-18T19:17:04","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74039","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00295,"riskScore":0.67,"affectedProduct":"Wazuh","affectedVersions":"<4.14.7","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74039","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74039","en":"https://www.redsauce.net/en/cves/CVE-2026-74039","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74039","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74039","de":"https://www.redsauce.net/de/cves/CVE-2026-74039","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74039","el":"https://www.redsauce.net/el/cves/CVE-2026-74039"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74039"}}
