When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module,
undisclosed HTTP/3 requests can cause NGINX worker processes to terminate
or cause other potential impact. This attack requires that a request be
specifically timed during the connection draining process, which the
attacker has no visibility and limited influence over.

Notes

Author Note
sbeattie QUIC support was added in nginx 1.25.0
