Record from redhat · Published October 21, 2026

A flaw was found in Go's crypto/x509 package. The certificate verification process fails to block trust in intermediate certificates associated with a compromised Certificate Authority (CA). A remote attacker presenting a certificate signed by these intermediate authorities can impersonate legitimate servers during secure connections. This flaw can enable an attacker to conduct a man-in-the-middle (MitM) attack to intercept or alter confidential communications.
