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.
