Vulnerability identifier: #VU59548
CSH Severity: Medium
CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]

CWE-ID: CWE-295
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of URI Subject Alternative Names. Node.js accepts arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type. A remote attacker can bypass name-constrained intermediates and perform spoofing attack.
