Apple Releases Urgent iOS 18.6 Update to Fix 29 Security Vulnerabilities

As of August 1, 2025, Apple has issued a critical software update for iPhone users to address a slew of security vulnerabilities. The iOS 18.6 update, released last week, includes fixes for 29 urgent security issues that could potentially expose users' sensitive data to hackers.

According to Apple's support page, some of the flaws relate to the iPhone's WebKit, which is used by the Safari web browser. These vulnerabilities could enable malicious websites to extract private information. Other bugs affect the device's audio and media processing frameworks, which are integral to a wide range of apps.

Cybersecurity experts are urging all iPhone owners to install the iOS 18.6 update as soon as possible. Josh Stein, VP of strategy and security at Jamf, emphasizes that while the vulnerabilities have not been exploited in the wild yet, users should not delay updating their devices. He states that "keeping devices up to date with the latest patches is one of the most effective ways to safeguard against attackers."

With the release of iOS 26 expected in the coming months, this is likely the last major security update before the next major iPhone software overhaul. Therefore, it is crucial for users to prioritize installing iOS 18.6 to ensure their devices remain protected in the interim.
