Last modified
CVE-2025-22870 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
