Important: go-fdo-server security update
Details

This package provides a server-side implementation of the FIDO Device Onboard (FDO) specification, written in Go. FDO is an open standard for the late binding of device credentials, allowing for automated and secure on-boarding of devices when they are first powered on in their final location.

Security Fix(es):

  • crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application (CVE-2026-33810)

  • encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818)

  • net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution (CVE-2026-56860)

  • net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853)

  • crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862)
