AI Analysis
Technical Summary
The advisory covers 13 CVEs affecting Node.js 22 and related libraries such as ip-address and undici. Vulnerabilities include cross-site scripting via improper HTML escaping (CVE-2026-42338), denial of service from unbounded memory growth in WebSocket frames (CVE-2026-12151), information disclosure due to improper cache-control header parsing (CVE-2026-9678), response queue poisoning on reused keep-alive sockets (CVE-2026-6733), weakening of cookie SameSite policy (CVE-2026-11525), denial of service via unlimited HTTP/2 ORIGIN frames (CVE-2026-48619), silent authority rebinding due to embedded-nul hostnames in TLS (CVE-2026-48930), unauthorized file metadata modification (CVE-2026-48935), denial of service via large input to subtle.encrypt() (CVE-2026-48933), certification validation bypass in TLS host verification (CVE-2026-48934), trust-policy bypass due to hostname matching inconsistency (CVE-2026-48928), information disclosure of proxy credentials via proxy tunnel error handling (CVE-2026-48615), and authentication bypass due to TLS hostname handling and unicode dot separator mismatch (CVE-2026-48618). The update rebases nodejs22 to the latest upstream Node.js 22 release for Red Hat Enterprise Linux 10.
Potential Impact
The vulnerabilities collectively impact the confidentiality, integrity, and availability of Node.js applications. They enable cross-site scripting attacks, denial of service conditions, information disclosure of sensitive data such as proxy credentials, authentication bypasses, and trust-policy bypasses. These issues could lead to incorrect response delivery, unauthorized file metadata changes, and weakened security policies, potentially affecting applications relying on Node.js 22 on Red Hat Enterprise Linux 10.
Mitigation Recommendations
Red Hat has released an updated nodejs22 package rebased to the latest Node.js 22 release that addresses all listed vulnerabilities. Users should apply this official update as per Red Hat's guidance at https://access.redhat.com/articles/11258. This update is included in Red Hat Enterprise Linux 10.2 and its extended update and lifecycle support variants. No additional mitigation steps are indicated beyond applying the official patch.
