Descriptions

A type confusion vulnerability could be triggered when resolving the "typeof" unary operator in Facebook Hermes prior to v0.10.0. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.

Una vulnerabilidad de confusión de tipo podría ser desencadenada al resolver el operador unario "typeof" en Facebook Hermes versiones anteriores a v0.10.0. Tenga en cuenta que esto sólo es explotable si la aplicación que usa Hermes permite una evaluación de JavaScript no confiable. Por lo tanto, la mayoría de las aplicaciones React Native no están afectadas
