Summary

NewsBreak for Android has a WebView JavaScript bridge that wrongly trusts data:text/html; pages, so a crafted page opened through the newsbreak://openweb deep link can call the bridge's getLoginInfo action. An attacker could use this to reveal a signed-in user's account information and session token after the user opens the malicious link.
