Apple Urgently Patches Zero-Day Vulnerability Exploited in Active Attacks
SAN FRANCISCO, Calif. — Apple has released an urgent security update addressing a critical zero-day vulnerability actively exploited by hackers targeting a broad range of its devices, including iPhones, iPads, Macs, Apple Watches, and Apple TVs. The flaw, identified as CVE-2026-20700, is a memory corruption vulnerability that could allow attackers to execute arbitrary code, potentially leading to spyware installation, unauthorized access, or silent device takeovers without user detection.
The vulnerability affects multiple operating systems, including iOS 26.3, iPadOS 26.3, macOS Tahoe 26.3, watchOS 26.3, tvOS 26.3, and visionOS 26.3. Apple confirmed that this flaw was already being exploited in targeted attacks, underscoring the urgency for users to install the latest security patches immediately. Devices that have not installed previous updates remain particularly vulnerable, as this zero-day was part of an infection chain combined with two earlier flaws patched in December 2025.
Cybersecurity experts warn that zero-day vulnerabilities like CVE-2026-20700 are especially dangerous because attackers exploit them before developers can issue fixes. The Cybersecurity and Infrastructure Security Agency recommends that users prioritize applying security updates promptly to mitigate risks posed by such exploits.
Apple’s swift response highlights the company’s commitment to securing its ecosystem, but users must remain vigilant. The update is available through the standard software update channels on all affected devices. Users can verify and install updates by navigating to Settings > General > Software Update on iPhones and iPads, System Preferences > Software Update on Macs, or the respective update menus on Apple Watch and Apple TV.
Security researchers emphasize that this incident serves as a reminder for all technology users—not only those on Apple platforms—to regularly check for and install system updates. The United States Computer Emergency Readiness Team advises that keeping software current is one of the most effective defenses against cyber threats.
In addition to patching this vulnerability, Apple continues to enhance its security infrastructure to protect users from increasingly sophisticated cyberattacks. The company’s security updates often include fixes for multiple vulnerabilities, reinforcing the importance of comprehensive and timely patch management.
For users concerned about the integrity of their devices, Apple provides detailed information about security content in updates on its official support site. Meanwhile, government agencies like the Federal Bureau of Investigation’s Cyber Division urge users to report any suspicious activity that could indicate exploitation attempts.
As cyber threats evolve, this latest zero-day exploitation underscores the critical need for users to maintain updated software and remain alert to security advisories. Apple device owners are strongly encouraged to install the February 2026 update without delay to safeguard their personal data and device functionality.
