On top of that, we have implemented HTTP/2 client, server and proxy. We have also developed load test and benchmarking tool for HTTP/2.\r\n\r\nSecurity Fix(es):\n\nnghttp2'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.(CVE-2026-58055)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"nghttp2","purl":"pkg:rpm/openEuler/nghttp2&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.58.0-4.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["libnghttp2-1.58.0-4.oe2403sp3.aarch64.rpm","libnghttp2-devel-1.58.0-4.oe2403sp3.aarch64.rpm","nghttp2-1.58.0-4.oe2403sp3.aarch64.rpm","nghttp2-debuginfo-1.58.0-4.oe2403sp3.aarch64.rpm","nghttp2-debugsource-1.58.0-4.oe2403sp3.aarch64.rpm"],"noarch":["nghttp2-help-1.58.0-4.oe2403sp3.noarch.rpm"],"src":["nghttp2-1.58.0-4.oe2403sp3.src.rpm"],"x86_64":["libnghttp2-1.58.0-4.oe2403sp3.x86_64.rpm","libnghttp2-devel-1.58.0-4.oe2403sp3.x86_64.rpm","nghttp2-1.58.0-4.oe2403sp3.x86_64.rpm","nghttp2-debuginfo-1.58.0-4.oe2403sp3.x86_64.rpm","nghttp2-debugsource-1.58.0-4.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2980"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58055"}],"database_specific":{"severity":"Medium"}}
