CVE-2026-42049Public exploit

Code execution via unescaped Gradle template value

Published Jul 14, 2026 · Updated Jul 14, 2026

Code injection in JADX before 1.5.6 allows attackers to execute arbitrary code by exporting and building a malicious APK. The Gradle exporter copies android:versionName into app/build.gradle as an unescaped Groovy string, allowing the manifest value to terminate the literal and inject statements. Execution requires a user to export the APK and build the generated project with Gradle or open it in Android Studio, after which injected code runs with that user's privileges.
