CVE-2026-16812 Command injection vulnerability in VeloCloud Orchestrator (VCO) on-premises allows unauthenticated remote attackers to access internal functionality and fully compromise the host system, impacting data managed by the orchestrator. This issue is known to be actively exploited. Hosted and Dedicated VCO versions have been pre-emptively patched. CRITICAL 10.0 1.0% 121
KEV PoC
CVE-2026-75945 Arista EOS 4.36.0 through 4.36.1F contains a race condition in IEEE 802.1X port-based Network Access Control that can leave a supplicant in an authorized state after an administrator explicitly issues the 'clear dot1x host all' deauthorization command. The flaw (CWE-459: Incomplete Cleanup) means that a device intended to be removed from the network may retain valid access, undermining the administrative action entirely. No public exploit code exists and SSVC exploitation status is confirmed as none; however, the integrity gap created - a device that should be denied access remaining authorized - is the primary concern for network access control posture.
