NVD Description

Note: Versions mentioned in the description apply only to the upstream npm package and not the npm package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

nghttp2's nghttpx proxy through 1.69.0 forwards an HTTP/1.1 Upgrade request that also carries a Content-Length header and body onto reusable keep-alive backend connections, re-adding the Upgrade and Connection headers while passing Content-Length verbatim. A backend that resolves the resulting ambiguous message in the attacker's favor enables HTTP request/response smuggling and cross-client response-queue poisoning.
