CVE-2026-33029: Nginxui Nginx UI

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, an input validation vulnerability in the logrotate configuration allows an authenticated user to cause a complete Denial of Service (DoS). By submitting a negative integer for the rotation interval, the backend enters an infinite loop or an invalid state, rendering the web interface unresponsive. This issue has been patched in version 2.3.4.

• Nginxui Nginx UI: before 2.3.4 (fixed in 2.3.4)
