Apple faces another cybersecurity emergency today. The tech giant swiftly released an urgent security update addressing a dangerous WebKit zero-day vulnerability. Identified as CVE-2025-24201, this security flaw lets hackers gain unauthorized access through malicious websites. Apple confirmed that hackers already targeted users in what they describe as “extremely sophisticated attacks.”

This critical vulnerability affects Apple’s entire ecosystem, including iPhones, iPads, Macs, and the recently launched Apple Vision Pro. Without immediate action, millions of Apple users remain vulnerable. Apple’s rapid response highlights the severity of the threat.

The vulnerability exists within WebKit, Apple’s browsing engine powering Safari. Users with WebKit Flaw become victims simply by visiting compromised websites, exposing their sensitive information and device security.

Apple urges users running the latest versions of iOS Sequoia, iPadOS, macOS Sequoia, and visionOS to update immediately. The company’s advisory strongly recommends enabling automatic updates to quickly receive critical security fixes.

Zero-day exploits are growing more common

Cybersecurity experts warn that zero-day exploits are growing more common. They emphasize the urgency of updating devices as soon as security patches become available. Neglecting this step leaves users highly vulnerable to exploitation and data breaches.

The CVE-2025-24201 vulnerability marks Apple’s third serious zero-day patched in 2025 alone. These frequent patches highlight the evolving threat landscape, where cybercriminals constantly search for new vulnerabilities to exploit.

According to Apple’s statement, attackers crafted malicious websites designed specifically to exploit this flaw in WebKit. The precise number of affected users remains unknown, but the attacks targeted specific individuals, hinting at potential espionage or surveillance.

Apple recommends that users immediately download and install these specific software versions to stay protected:

• iOS 18.3.2 and iPadOS 18.3.2 – iPhone XS and later, 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
• macOS Sequoia 15.3.2 – Macs running macOS Sequoia
• Safari 18.3.1 – Macs running macOS Ventura and macOS Sonoma
• visionOS 2.3.2 – Apple Vision Pro

Security professionals emphasize the importance of vigilance, urging users to remain aware of threats. Timely software updates remain one of the most effective defenses against cyberattacks.

This year alone, Apple has confronted multiple zero-day exploits, underscoring the ongoing cybersecurity challenges faced by major tech giants. Users should remain proactive in protecting their devices to avoid falling victim to sophisticated cyberattacks.
