Multiple NGINX Flaws Let Remote Attackers Crash Servers and Execute Malicious Code

F5 has disclosed three serious security flaws in NGINX Plus and NGINX Open Source that can let remote, unauthenticated attackers crash worker processes by sending crafted HTTP requests. The flaws are tracked as CVE-2026-97205, CVE-2026-93479, and CVE-2026-15176.

F5 published the three advisories on October 14, 2026, and rated every issue High at 8.1 under CVSS v3.1 and Critical at 9.2 under CVSS v4.0. The bugs do not make every NGINX server vulnerable by default because each one needs a specific software version and configuration.

F5’s advisories do not report active exploitation of these three newly disclosed flaws.
