A certificate containing \u0060DNS:127.0.0.1\u0060 and no \u0060IP Address:127.0.0.1\u0060 SAN was therefore accepted, while the same certificate is correctly rejected for \u0060127.0.0.1\u0060. Exploitation requires a certificate with a numeric DNS SAN issued by a CA trusted by the client, and a platform resolver that accepts these spellings, such as glibc.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.",
