CVE-2026-6060Network attack vector

Webserver termination via unbounded SQL Box processing

Published Apr 20, 2026 · Updated Apr 20, 2026

Uncontrolled resource consumption in OTRS 7.0.x, 8.0.x, and 2023.x through 2026.2.x allows remote authenticated users to kill the webserver. The administrative SQL Box processes a resource-intensive database operation without limiting or throttling its resource allocation. Administrative privileges and user interaction are required, and successful exhaustion terminates the webserver process and interrupts service.
