Today we are releasing updates to NGINX Open Source and NGINX Plus in response to the recent discovery of vulnerabilities in many implementations of HTTP/2. We strongly recommend upgrading all systems that have HTTP/2 enabled.

In May 2019, researchers at Netflix discovered a number of security vulnerabilities in several HTTP/2 server implementations. These were responsibly reported to each of the vendors and maintainers concerned. NGINX was vulnerable to three attack vectors, as detailed in the following CVEs:

We have addressed these vulnerabilities, and added other HTTP/2 security safeguards, in the following NGINX versions:

  • NGINX 1.16.1 (stable)
  • NGINX 1.17.3 (mainline)
  • NGINX Plus R18 P1
