The record
During device acquisition, `getPathToLocalCopy()` constructs local filesystem paths for downloaded APKs using a filename component extracted by `extractFileName()`. The extraction splits on `==/` and takes the remainder without sanitization. If a compromised device returns a crafted APK path containing traversal sequences, `filepath.Join` resolves them, allowing the file to be written outside the intended `apks/` directory. Practical exploitability is limited because Android enforces strict package path formats under `/data/app/` and does not allow apps to register paths containing traversal sequences. Rated Informational as a defense-in-depth concern.
