Nginx 1.29.8 - Critical Security Updates Released

Active exploitation or massive impact — immediate action required
Basically, Nginx has new updates that fix serious security problems.
Nginx and FreeNginx have released critical updates to enhance security and fix vulnerabilities. Web server admins must update immediately to protect their infrastructure.
What Happened
On April 7, 2026, Nginx 1.29.8 and the FreeNginx project released critical updates that every web server administrator must prioritize. These updates introduce essential security features, enhance cryptographic compatibility, and fix crucial bugs to ensure robust server performance against modern cyber threats.
New Security Features
One of the standout upgrades in Nginx 1.29.8 is the support for OpenSSL 4.0. As cyber threats evolve, maintaining compatibility with the latest cryptographic standards is vital for securing data in transit. This integration allows administrators to use advanced encryption protocols, protecting sensitive web traffic against interception techniques and vulnerabilities.
Additionally, the new max_headers directive limits the maximum number of HTTP headers accepted in client requests. This feature helps mitigate resource exhaustion attacks and prevents buffer overflow vulnerabilities that denial-of-service attackers often exploit.
Bug Fixes
The update also addresses specific processing errors that could negatively impact server stability. For instance, a bug related to HTTP 103 (Early Hints) responses has been resolved, ensuring that browsers receive pre-load instructions smoothly. Furthermore, an internal routing issue affecting request_port and is_request_port variables in subrequests has been fixed, enhancing the accuracy of internal server routing and logging mechanisms.
What You Should Do
Cybersecurity experts strongly advise system administrators using Nginx or FreeNginx to apply the 1.29.8 update immediately. This action will help reduce the attack surface and secure web infrastructure against potential threats. Keeping server software up-to-date is crucial in maintaining a strong defense against cyber threats.
