Apple iOS and macOS Group Facetime Vulnerability
CVE-2019-6223 is a security vulnerability in Apple iOS and macOS, added to CISA KEV on November 3, 2021. Patch priority: Plan to patch.
What it is
Apple iOS and macOS Group FaceTime contains an unspecified vulnerability where the call initiator can cause the recipient's Apple device to answer unknowingly or without user interaction.
VulnCheck tracked exploitation 999 days before CISA's KEV listing. VulnCheck's broader catalog of in-the-wild exploitation evidence picked this up before it landed on CISA's formal list. Per-CVE fact about this entry; not a population claim about lead time in general.
Who's affected
Affects anyone running Macs, iPhones, or iPads in the office. For a small practice, Apple endpoints are typically how staff handle email, browse client portals, and store local case files — exploitation gives an attacker access to that data on the device.
What to do
Apply updates per vendor instructions.
If you don't have someone in-house to verify the patch deployed across every endpoint — or you're not sure whether you're affected — that's exactly the kind of triage we do. Book a free 20-minute triage call.
Insurance readiness
Your insurer will ask if this is patched.
Unpatched entries on CISA's Known Exploited Vulnerabilities list are exactly what cyber-insurance carrier questionnaires probe for, and knowing which controls they check is how you keep a renewal from stalling.

CVSS base score: 7.5 — HIGH
CISA due date
Federal deadline: May 3, 2022. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
EPSS
EPSS score: 2.6% — higher than 84% of all scored CVEs.
EPSS estimates the probability of exploitation activity in the next 30 days. Every entry on this site is already confirmed exploited, so read it as relative urgency among the things you still have open, not as permission to wait.
