summary: Usage of IPv6 zone IDs can bypass URI name constraints in crypto/x509
description: |-
    A certificate with a URI which has a IPv6 address with a zone ID may incorrectly
    satisfy a URI name constraint that applies to the certificate chain.

    Certificates containing URIs are not permitted in the web PKI, so this only
    affects users of private PKIs which make use of URIs.
