Frequently Asked Questions
Which components are implicated by the security fixes?
The update addresses issues in the brace-expansion and undici dependencies, as well as Node.js itself. The listed impacts include denial of service, certificate validation bypass, TLS hostname bypass, and hostname truncation involving a NUL character.
Which denial-of-service conditions are identified?
The advisory lists uncontrolled recursion and stack exhaustion from crafted nested brace patterns in brace-expansion. It also lists undici denial-of-service conditions involving excessive content encodings and TLS renegotiation with a mismatched certificate.
What certificate-related issues does this update address?
It fixes an undici Agent issue in which TLS options can be dropped, allowing certificate validation bypass. It also fixes a Node.js TLS hostname validation bypass involving non-canonical IP hostnames.
