Apple Safari/WebKit: Use-after-free allows arbitrary code execution
Summary
Apple Safari and WebKit-based components on iOS, iPadOS, macOS and visionOS contain a use-after-free memory issue. An attacker can run arbitrary code by sending crafted web content that the victim opens. The attack needs no privileges, but a user must act, typically by visiting a malicious page.

- Safari before 27.2
- iOS and iPadOS before 26.7.2 and before 27.2
- macOS before 27.2 (macOS Golden Gate)
- visionOS before 27.2
Fixed in
- Safari 27.2
- iOS 26.7.2 and iPadOS 26.7.2
- iOS 27.2 and iPadOS 27.2
- macOS Golden Gate 27.2
- visionOS 27.2
Workaround
Unknown.
Exploitation
- Not listed in CISA KEV.
- CISA SSVC: exploitation none, automatable no.
- EPSS below 1%.
- Apple advisories reviewed do not flag this issue as exploited in the wild.
- No public proof of concept found.
Our recommendation
- Update Safari and all Apple devices to the fixed versions without delay, prioritising devices used for web browsing.
- Check the Apple advisories for each product to confirm the fixed build.
- Monitor for new Apple security releases and known exploitation reports.
