Binance told iPhone users about a public flaw in iOS, the operating system that runs Apple's iPhone. The flaw is a sandbox escape called worse_query, which can let an app break out of the limits meant to keep it separate from other apps.

According to the warning, a malicious app could use this flaw to read seed phrases and private keys saved by other apps. A seed phrase is a list of words that restores access to a crypto wallet, and a private key does a similar job.

Apple's updates released on Nov. 9 do not mention the bug. Binance told users to delete sideloaded apps, which are apps installed from outside the App Store.

For people who keep crypto on an iPhone, the warning points to a risk that wallet data could be read by other software on the same phone. The issue remains open until Apple releases a fix.
