Node.js Issues Security Updates Patching Ten Vulnerabilities Including High-Severity TLS Name Verification Bypasses
The Node.js project released security updates on October 21 for release lines 26, 24, and 22, addressing ten vulnerabilities with four rated high severity. The most critical issue, CVE-2026-111497, resides in the Brotli decoder and involves an out-of-bounds write that could enable remote code execution across all three supported lines. Two additional high-severity flaws affect TLS name verification: CVE-2026-105483 bypasses checks when addresses contain full-width digits, while CVE-2026-106069 fails on imprecise IP address resolution, potentially allowing a certificate to be accepted for an unintended destination. A fourth high-severity vulnerability, CVE-2026-105482, causes the dns.resolve function to truncate names containing null characters, creating inconsistencies between queried and resolved names. Medium-severity issues include out-of-order processing in HTTP socket keep-alive, improper certificate validation for non-standard IPv4 addresses, and repeated cryptographic random values in snapshot initialization and single-executable applications affecting crypto.randomUUID and crypto.randomInt. The updates also refresh c-ares, CA certificates, Undici, OpenSSL, and SQLite, with recommendations to test HTTPS outbound connections, DNS handling, Brotli-compressed content, and permission-restricted workloads.
