iOS Sandbox Escape Is Public, and Apple Hasn’t Confirmed a Fix
Public iOS sandbox escape 'worse_query' allows apps to read local files, potentially exposing sensitive data.
A public iOS sandbox escape vulnerability, named 'worse_query', allows malicious apps to read local files from other applications, potentially exposing seed phrases, private keys, and login credentials. The exploit affects iOS versions 26.7.1, 27.0.1, and 27.2. While Apple has released updates, they have not confirmed a fix for this specific issue. No attacks or data theft have been reported by Binance or the researcher who published the proof-of-concept code.

The lesson from this incident
Full lessonA publicly disclosed iOS sandbox escape vulnerability, dubbed 'worse_query', allows malicious applications to read files belonging to other apps, potentially exposing cryptocurrency seed phrases, private keys, and login credentials. The core problem is that a proof-of-concept exploit is publicly available while Apple has not confirmed whether its recent updates actually address the flaw, leaving users in an ambiguous security state. This matters because attackers can weaponize public exploit code quickly, and the absence of vendor confirmation makes it impossible for defenders to know whether patching resolves the risk. Organizations and individuals relying on iOS devices to store sensitive financial or identity data face elevated exposure until Apple explicitly validates a fix.
