CVE-2025-22870 (GCVE-0-2025-22870)
Vulnerability from cvelistv5

Summary
Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.
