F5 SIRT (f5sirt@f5.com CNA) via NVD
F5 is its own CVE Numbering Authority. VulniPulse ingests F5's CVEs from the NVD CNA feed (f5sirt@f5.com), each linking to its my.f5.com / support.f5.com security article. Covers BIG-IP (LTM, ASM/Advanced WAF, APM, AFM), BIG-IP Next, BIG-IQ, NGINX / NGINX Plus, F5OS and Distributed Cloud — internet-facing application-delivery and security appliances that are repeatedly mass-exploited (e.g. the CVE-2023-46747 RCE), so a patch-now enterprise audience.

Medium [CVE-2025-1695] In NGINX Unit before version 1.34.2 with the Java Language Module in use, undisclosed requests can
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.
