CVE-2026-18924: use-after-free in the cleanup of HTTP/2 server push
transfers, because a pushed transfer did not inherit the parent handle's
share and could therefore outlive a shared connection
CVE-2026-80230: public key pinning was not enforced when the server
presented no certificate and both peer and host verification were
disabled, so an unauthenticated connection succeeded where it should have
been rejected
CVE-2026-82209: a cookie whose Domain attribute exactly matched a public
suffix was stored with wildcard domain scope instead of being coerced to
host-only, so it was sent to arbitrary sibling subdomains under that
public suffix
remove upstream test1701, which performs an HTTP/2 Upgrade on an HTTP/1.1
POST; nghttp2 1.43 no longer supports Upgrade requests carrying a body,
so the test fails against the nghttpx in the build root
