Type:
security
Severity:
Important
Release date:
2026-10-23 07:59:03 UTC
Description:
- CVE-2026-39821: reject xn-- labels that decode to all-ASCII in the vendored golang.org/x/net/idna package; the check shipped in x/net v0.56.0 is compiled out when built with Go 1.26 - require golang >= 1.26.6: the Go standard library fixes come from the build toolchain, an older golang would silently reopen them
