Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the process that inserts the android:versionName value from an AndroidManifest into the generated app/build.gradle Groovy template without proper sanitization. An attacker can execute arbitrary code by crafting a malicious APK that injects Groovy code, which is then run when the exported Gradle project is opened or built.
