CVE-2022-0455 Inappropriate implementation in Google Chrome on Android before 98.0.4758.80 allowed a remote attacker to spoof the contents of the Omnibox.

CVE-2022-0455 Inappropriate implementation in Google Chrome on Android before 98.0.4758.80 allowed a remote attacker to spoof the contents of the Omnibox.

A remote attacker could host a specially crafted website that is accessed through the Chrome browser on an Android device and could potentially trick a user into entering personal information within the Omnibox by reading the text. This issue affected all Android versions prior to version 4.4.4, including Android O. Google released Android O with an updated version of Chrome that removes this issue. Due to incorrect assumptions made in the original patch, this issue was not properly addressed in the Android O update to Chrome, which resulted in it being reintroduced via the same patch in Android WebView.

This issue affected all Android versions prior to version 4.4.4, including Android O. Google released Android O with an updated version of Chrome that removes this issue.
