The server demonstrates robust security practices, especially in command execution. It uses allowlists for ADB subcommands and strong regular expressions (`DANGEROUS_SHELL_CHARS`) to validate user-provided arguments, preventing shell injection. Android's automation server runs via instrumentation, isolated on the device, and requires explicit `adb forward` for host communication. JSON parameter serialization for the automation client is handled by Gson, mitigating JSON injection risks. No hardcoded secrets or malicious patterns were detected. Reflection is used for advanced UI hierarchy dumping, which is a common, well-justified technique in mobile automation tools (like Maestro) but inherently carries a minor risk of breaking with future Android versions.
