New Nginx Exploit
A proof-of-concept exploit for a critical vulnerability in Nginx has been published on GitHub by the security research group DepthFirstDisclosures. The exploit, named Nginx-Rift, targets a buffer overflow in the HTTP/2 module, enabling remote code execution without authentication. Affected versions include Nginx 1.25.x and earlier. The disclosure includes a detailed technical write-up and a working exploit script. Administrators are urged to upgrade to Nginx 1.26.0 or apply the vendor's patch immediately. The vulnerability was responsibly disclosed to the Nginx team on April 30, 2026, and a fix was released on May 10. However, the public exploit release has raised concerns about widespread exploitation, especially given Nginx's prevalence as a web server and reverse proxy.
This exploit puts millions of Nginx servers at risk of remote takeover.
