GHSA-3J75-7JC2-VQCG

Vulnerability from github – Published: 2022-05-24 17:18 – Updated: 2026-08-19 15:31

Details

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 was being used for JS-to-native also, but it isn't needed in this case, and its usage was also leaking this token. This vulnerability affects Firefox for iOS < 25.

Severity

7.5 (High)
