CVE-2026-78660HTTP/2 transport accepts malformed framing-related headers in net/http

Go standard library net/http; Go standard library net/http/internal/http2; golang.org/x/net golang.org/x/net/http2 Veröffentlicht: (vor 1 Monat)

Beschreibung

Historically, we have been rather lax about malformed framing-related headers in our HTTP/2 implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client when acting as a reverse proxy. If the HTTP/1 client also does not behave strictly enough, this can result in response smuggling.

Schwachstellentyp (CWE): CWE-444
