Apple Rushes Out Critical iOS Update to Patch Dangerous Image File Exploit—What You Need to Know Now
Apple just dropped an emergency iOS update—and it’s not one you want to sleep on. A newly discovered image file exploit could let attackers bypass security protections, potentially gaining access to your device without lifting a fingerprint.
How It Works—And Why It’s Nasty
The vulnerability hides in plain sight: a maliciously crafted image file. Open it, and your iPhone could be exposed. No clicks, no warnings—just instant risk.
Timing Is Everything—Especially for Apple
This isn’t just another bug fix. Rushing out a patch mid-cycle signals how serious this is. Apple’s moving at breakneck speed to shut this down before it spreads.
Zero-Day in the Wild? Maybe.
While Apple hasn’t confirmed active attacks, the rapid response suggests they aren’t taking chances. If you’re still running an older iOS version, consider this your wake-up call.

Affected devices and update availability
The iOS 18.6.2 update covers all iPhones released since 2018, beginning with the iPhone XS, XS Max, XR, and the second- and third-generation iPhone SE. The patch also extends to Apple’s latest devices, including the iPhone 16 series and iPhone 16e.
Supported iPad models include the iPad Pro 13-inch, iPad Pro 12.9-inch (2nd generation and later), iPad Pro 11-inch (1st generation and later), iPad Pro 10.5-inch, iPad Air (3rd generation and later), iPad (6th generation and later), and iPad mini (5th generation and later).
The update is also available for Apple’s Mac computers running the three most recent versions of macOS. The tech giant is asking users not to wait for the automatic rollout and instead apply the patch manually, as the auto update could take time reaching all devices.
How did update 18.6.1 make devices vulnerable?
According to several security analysts, the flaw is an out-of-bounds write vulnerability, a type of bug that allows attackers to access or manipulate sections of device memory that should normally be restricted.
Pieter Arntz, a former Microsoft consultant and researcher at cybersecurity firm Malwarebytes, explained in a blog post that the vulnerability could allow attackers to insert and run code in “inaccessible” parts of memory.
“Such a flaw in a program allows it to read or write outside the bounds the program sets, enabling attackers to manipulate other parts of the memory allocated to more critical functions,” he wrote.
Arntz mentioned adversaries could exploit the bug by creating a malicious image file that corrupts memory as soon as the device processes it, even without user interaction. He compared the attack to so-called zero-click exploits, where spyware or malware is triggered simply by receiving or processing malicious content.
“Processing such a malicious image file WOULD result in memory corruption,” he said. “Memory corruption issues can be manipulated to crash a process or run an attacker’s code.”
Apple has admitted it had received reports of the flaw being used in targeted attacks against certain individuals, but did not identify the victims.
Sean Wright, head of application security at Featurespace, believes the exploit was too complex to be deployed on a wide scale.
“Thankfully, the exploit does appear to be complex and likely only exploited in a very targeted attack, so most ordinary users are unlikely to become a victim,” Wright told Forbes. “But I would still highly recommend applying the fix as soon as possible to be on the SAFE side.”
