Product | Affected Versions

Safari | 18.2 and earlier
visionOS | 2.2 and earlier
iOS | 18.2 and earlier
iPadOS | 18.2 and earlier
macOS Sequoia | 15.2 and earlier
watchOS | 11.2 and earlier
tvOS | 18.2 and earlier

How the Exploit Works

The vulnerability exploits a flaw in the way the affected operating systems process certain types of web content. If a user navigates to a web page or is persuaded to click on a link that contains maliciously crafted content, the flaw in the system’s processing can lead to memory corruption. This, in turn, could give an attacker the ability to execute arbitrary code, potentially leading to system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited using a maliciously crafted HTTP request.

GET /malicious-web-content HTTP/1.1
Host: target.example.com
User-Agent: Mozilla/5.0 (iPad; CPU OS 18_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Mobile/15E148 Safari/604.1
{ "malicious_payload": "..." }

Mitigation

The vendors have already addressed the issue in the latest versions of their respective software (Safari 18.3, visionOS 2.3, iOS 18.3, iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, tvOS 18.3). Users are strongly advised to update their systems to the latest versions as soon as possible. Until the updates can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation measures.
