HTTP/3 downgrade desync via a QUIC FIN! This is a really nice finding. There used to be a significant cognitive & fiddly-coding barrier to testing lower-level HTTP/2 & 3 techniques but AI has largely eliminated it. As ever, the fix is... upstream HTTP/1 must die!

HAProxy HTTP/3 -> HTTP/1 Desync: Cross-Protocol Smuggling via a Standalone QUIC FIN (CVE-2026-33555)

One zero-byte QUIC packet is enough to desynchronize HAProxy’s backend connection pool and smuggle HTTP requests across unrelated users — even users on a completely different frontend protocol.
