  "details": "## Summary\n\nIn versions of cryptography prior to 46.0.5, DNS name constraints were only validated against SANs within child certificates, and not the \"peer name\" presented during each validation. Consequently, cryptography would allow a peer named `bar.example.com` to validate against a wildcard leaf certificate for `*.example.com`, even if the leaf\u0027s parent certificate (or upwards) contained an excluded subtree constraint for `bar.example.com`.\n\nThis behavior resulted from a gap between RFC 5280 (which defines Name Constraint semantics) and RFC 9525 (which defines service identity semantics): put together, neither states definitively whether Name Constraints should be applied to peer names. To close this gap, cryptography now conservatively rejects any validation where the peer name would be rejected by a name constraint if it were a SAN instead.\n\nIn practice, exploitation of this bypass requires an uncommon X.509 topology, one that the Web PKI avoids because it exhibits these kinds of problems. Consequently, we consider this a medium-to-low impact severity.\n\nSee CVE-2025-61727 for a similar bypass in Go\u0027s `crypto/x509`.\n\n## Remediation\n\nUsers should upgrade to 46.0.6 or newer. \n\n## Attribution\n\nReporter: @1seal",
