Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Correct product CPE.
