Apple Releases Critical WebKit Security Update: How West Houston Businesses Can Protect Their Devices
Critical WebKit Zero-Day Vulnerability Patched
Apple has just released emergency security updates to address a critical WebKit vulnerability that has been exploited in what the company describes as “extremely sophisticated” targeted attacks. The vulnerability, tracked as CVE-2025-24201, affects WebKit—the browser engine that powers Safari and many other apps across Apple’s ecosystem.
Understanding the Exploit
According to Apple’s security advisories released on March 11, 2025, the vulnerability is an out-of-bounds write issue in WebKit that could allow attackers to:
- Use maliciously crafted web content to break out of the Web Content sandbox
- Execute unauthorized actions on affected devices
- Potentially gain control over targeted devices
The company noted that this is a “supplementary fix for an attack that was blocked in iOS 17.2” and acknowledged being “aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.”
Affected Apple Products
The WebKit vulnerability impacts a wide range of Apple devices, including:
- iPhones: iPhone XS and later models
- iPads: iPad Pro 13-inch, iPad Pro 12.9-inch (3rd generation and later), iPad Pro 11-inch (1st generation and later), iPad Air (3rd generation and later), iPad (7th generation and later), and iPad mini (5th generation and later)
- Macs: All Macs running macOS Sequoia
- Vision Pro: All Apple Vision Pro devices
Recommended Remediation Steps
To protect your devices from this vulnerability, Apple has released the following security updates:
- iOS 18.3.2 and iPadOS 18.3.2: Available via Settings > General > Software Update
- macOS Sequoia 15.3.2: Available through Apple menu > About This Mac > Software Update
- visionOS 2.3.2: Available through the system settings on Vision Pro
- Safari 18.3.1: Available for users of older macOS versions
Given the serious nature of this vulnerability and confirmation of active exploitation, we strongly recommend installing these updates immediately, even though the attacks appear to be highly targeted rather than widespread.
Rising Trend in Apple Security Issues
This marks the third zero-day vulnerability Apple has patched in 2025, following similar emergency patches in January (CVE-2025-24085) and February (CVE-2025-24200). Last year, Apple addressed six zero-days, which was already a concerning number—though significantly lower than the twenty zero-day vulnerabilities patched in 2023.
