GHSA-qxp5-gwg8-xv66
HTTP Proxy bypass using IPv6 Zone IDs in golang.org/x/net
Quick fix
GHSA-qxp5-gwg8-xv66 — golang.org/x/net: upgrade to the fixed version with the command below.
go get golang.org/x/net@v0.36.0Details
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.
