Description Guilherme de Almeida Suckevicz 2022-01-14 19:34:20 UTC

Node.js converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.

Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection.
