MobSF is a mobile application security testing tool used. Prior to 4.5.1, find_icon_path_zip in mobsf/StaticAnalyzer/views/android/icon_analysis.py uses the Android manifest android:icon value to construct paths under the scan resource directory without rejecting traversal or verifying containment, allowing an authenticated user to upload a crafted ZIP or APK that reads a server file with an ALLOWED_EXTENSIONS suffix, copies it to DWD_DIR as the predictable name -icon., and retrieves it through the /download/ endpoint. The same behavior provides a file-existence oracle through the icon_path report field. This issue is fixed in version 4.5.1.
