Overview
hermes-engine is an A JavaScript engine optimized for running React Native on Android
Affected versions of this package are vulnerable to Out-of-Bounds. An out-of-bounds read/write vulnerability when executing lazily compiled inner generator functions allows attackers to potentially execute arbitrary code via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.
