CVE-2019-0219Public exploitNetwork attack vector

Privilege escalation via malformed callback identifier

Published Jan 14, 2020 · Updated Aug 4, 2024

Privilege escalation in Apache Cordova InAppBrowser 3.0.0 and earlier allows remote attackers to run JavaScript in the host app WebView. The Android URL-override handler accepts a crafted gap-iab URI and passes its malformed callback identifier into JavaScript evaluated by the main Cordova WebView. Exposure requires an Android Cordova application to load attacker-controlled web content in InAppBrowser; successful code runs with the main WebView's Cordova bridge access.
