A remote attacker can exploit this vulnerability by sending a specially crafted HTTP request that includes a header named `__proto__`. When a Node.js application processes this request and attempts to access distinct headers, it encounters an unhandled error, leading to an application crash. This can result in a Denial of Service (DoS), making the affected service unavailable to users."], "mitigation": {"lang": "en:us", "value": "Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}, "name": "CVE-2026-21710", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "nodejs22", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "nodejs24", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "nodejs:20/nodejs", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "nodejs:22/nodejs", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "nodejs:24/nodejs", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "nodejs:20/nodejs", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "nodejs:22/nodejs", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "nodejs:24/nodejs", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2026-03-30T19:07:28Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-21710\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-21710\nhttps://nodejs.org/en/blog/vulnerability/march-2026-security-releases"], "threat_severity": "Important"}
