# CVE-2024-23222: Apple Multiple Products WebKit Type Confusion Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Apple Multiple Products. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-01-23, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-02-13 ; treat that as the outer limit, not the target.
- EPSS 10.6% , percentile 96: FIRST’s model estimates a 10.6% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.

## What it is

A type confusion issue was addressed with improved checks. This issue is fixed in Safari 17.3, iOS 15.8.7 and iPadOS 15.8.7, iOS 16.7.5 and iPadOS 16.7.5, iOS 17.3 and iPadOS 17.3, macOS Monterey 12.7.3, macOS Sonoma 14.3, macOS Ventura 13.6.4, tvOS 17.3, visionOS 1.0.2. Processing maliciously crafted web content may lead to arbitrary code execution. This fix associated with the Coruna exploit was shipped in iOS 17.3 on January 22, 2024. This update brings that fix to devices that cannot update to the latest iOS version.
