Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Path Traversal: The Expand utility was vulnerable to a classic Zip Slip vulnerability where crafted archive entry paths could escape the target directory during extraction. Developers must ensure all file-writing paths utilize canonical path validation against a trusted base directory before writing content to disk.

Command Injection: Command execution via CmdShell was vulnerable to side-channel execution of registry-configured AutoRun commands because cmd.exe was invoked without defensive flags. Developers must guarantee that execution shells enforce strict argument policies, such as executing cmd.exe with the /D flag, and carefully escape double-quoted shell arguments.
