The Sleipnir Mobile application 2.12.1 and earlier and Sleipnir Mobile Black Edition application 2.12.1 and earlier for Android provide Geolocation API data without verifying user consent, which allows remote attackers to obtain sensitive location information via a web site that makes API calls.
The Sleipnir Mobile application before 2.1.0 and Sleipnir Mobile Black Edition application before 2.1.0 for Android do not properly implement the WebView class, which allows remote attackers to obtain sensitive information via a crafted application.
