Does this matter?
Lower severity and a low EPSS score (0.78%). Track it; it rarely justifies an emergency change on its own.
Description
For native-to-JS bridging the app requires a unique token to be passed that ensures non-app code can't call the bridging functions. That token could leak when used for downloading files. This vulnerability affects Firefox for iOS < 26.
