Binance Warns Against iOS Vulnerability That Affects iPhone Crypto Holders—Is the Issue Fixed?

A newly disclosed security flaw in iOS is raising serious alarm among cryptocurrency users on iPhones, and what makes the situation especially troubling is that the patch has not arrived yet.

Binance was among the first major platforms to issue a public warning, and what researchers are saying about the vulnerability's current status is not reassuring.

Binance Warns Against iOS Vulnerability on Crypto

Binance posted a warning on its official X account , alerting iPhone users to a security vulnerability tracked as "worse_query," describing it as a flaw that allows malicious apps to read local files stored by other apps on the same device. The concern for cryptocurrency holders is direct: seed phrases, private keys, and login credentials stored within crypto apps on the device are all potentially accessible to any app exploiting this vulnerability.

Binance was explicit that the flaw is not unique to its own platform but is instead a system-level issue within iOS itself. "This is an iOS-level issue, not unique to Binance," the exchange stated in its post, adding that the vulnerability affects iOS versions 26.7.1, 27.0.1, and 27.2.

The vulnerability was disclosed by security researchers @0xjohnny and @forcequitOS, who published a proof-of-concept demonstration on GitHub showing how the flaw can be used to bypass iOS sandbox protections.
