Nginx released versions 1.30.5 and 1.31.6 to address a buffer overflow vulnerability in HTTP/3 functionality identified as CVE-2026-90439. The updates are available as source code and pre-built packages for Linux systems.
Portspan is a self-hosted ngrok alternative that exposes local development ports via predictable wildcard subdomains. It uses frp for tunneling and routing, Nginx for TLS termination, and provides setup scripts, security documentation, and client tooling for Linux servers.
NGINX 1.31.5 introduced predicate locations, a feature enabling native routing of API traffic based on any variable rather than just URLs. The update addresses the problem that modern applications often place routing logic in headers and request bodies instead of following HTTP conventions, allowing NGINX to route traffic more efficiently using variables mapped through the map module.
