CVE-2025-1695: NGINX Unit Java Vulnerability

First published: Mon Mar 03 2025(Updated: )

In NGINX Unit before version 1.34.2 with the Java Language Module in use, undisclosed requests can lead to an infinite loop and cause an increase in CPU resource utilization. This vulnerability allows a remote attacker to cause a degradation that can lead to a limited denial-of-service (DoS). There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
