Users of iPhone and iPad are advised to upgrade to iOS 18.6 to address a severe security vulnerability
In a recent turn of events, Apple device users are urged to update their devices to the latest versions of iOS/iPadOS and macOS, following the discovery of multiple severe security vulnerabilities in iOS/iPadOS 18.6.
These vulnerabilities, if exploited, could potentially allow attackers to compromise your device without your knowledge, accessing personal data such as passwords, messages, photos, and files. One of the most critical vulnerabilities, CVE-2025-6558, is a zero-day vulnerability in WebKit.
The vulnerabilities can be exploited merely by visiting or interacting with websites or content that serve malicious image files. This necessitates urgent updates to close the security gap and protect your data and devices from cyberattacks.
Apple has addressed the issue through improved bounds checking in iOS 18.6.2, iPadOS 18.6.2, and macOS Sequoia 15.6.1 updates, which were released on August 20, 2025. The vulnerabilities affect devices starting from iPhone XS and later, various iPad Pro models, iPad Air 3rd generation and later, and iPad mini 5th generation and later.
Experts warn that such vulnerabilities often become subject to broader, opportunistic attacks once patches are released, increasing the risk for all users. Therefore, it is strongly recommended that all users of affected Apple devices update to the latest security releases immediately.
In addition to updating your device, it's essential to exercise caution when visiting websites or opening image files from untrusted sources. Stay informed of Apple's security updates and install them promptly as new patches become available to guard against emerging threats.
For organizational contexts, ensure timely deployment of these updates in enterprise device management systems and monitor for unusual device behavior that might indicate exploitation attempts.
If you suspect a cyber threat, you can report it to the National Cyber Security Agency (NCSA) of Thailand via email at [email protected], phone at 0-2114-3531 (24/7), or LINE at @thaicert.
