Security researchers have identified critical vulnerabilities in the WebKit engine that affect virtually every internet user, as the component powers the majority of web browsing on mobile devices.
Exploitation of these flaws can occur when a user inadvertently visits a malicious site, potentially allowing unauthorized code execution or data theft.
Users of devices running iOS 26 are advised to install the latest 26.5.2 update without delay to mitigate the identified risks.
A subsequent iOS 26.6 release is scheduled for July, and a third developer beta of the version was made available today, indicating continued effort to strengthen the platform.
To apply iOS 26.5.2, open the Settings application, select General, choose Software Update, and follow the on-screen prompts to complete the installation.
