Summary
nghttp2 security update
Details

The framing layer of HTTP/2 is implemented as a form of reusable C library. 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.

Security Fix(es):

A security vulnerability exists in nghttp2 library where missing state validation leads to assertion failure, which can be exploited by attackers to cause denial of service.(CVE-2026-27135)

Severity
7.5 (High)
