Description
This security bulletin contains information about 1 security vulnerability.
1) Information disclosure (CVE-ID: CVE-2020-6830)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
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.
Remediation
Install update from vendor's website.
