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.

High [CVE-2025-31644] When running in Appliance mode, a command injection vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell…
When running in Appliance mode, a command injection vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell (tmsh) command which may allow an authenticated attacker with administrator role privileges to execute arbitrary system commands. A successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Medium [CVE-2025-43878] F5OS: When running in Appliance mode, an authenticated attacker assigned the Administrator or Resource Administrator role
When running in Appliance mode, an authenticated attacker assigned the Administrator or Resource Administrator role may be able to bypass Appliance mode restrictions utilizing system diagnostics tcpdump command utility on a F5OS-C/A system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
