golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

CVE-2026-69248

Cryptography (Python) prior to 49.0.0 may accept a leaf certificate with a wildcard SAN (*.example.com) when a constrained sub-CA permits foo.example.com, due to DNSConstraint::matches treating a wildcard as matching the permitted constraint. This can allow escaping to sibling names (e.g., bar.ex...
