CVE-2025-10630Network attack vector

Authenticated service interruption via unbounded regex evaluation

Published Sep 19, 2025 · Updated Sep 24, 2025

Regular expression denial of service in Grafana-Zabbix before 6.0.2 allows remote authenticated users to interrupt service via regex queries. The regex query path compiles and evaluates user-supplied patterns without an effective timeout, allowing crafted expressions to monopolize CPU. Low-privileged Grafana access is required; successful requests can drive CPU usage to its maximum and degrade availability.
