How CLI Automation Becomes an Exploitation Surface
How CLI Automation Becomes an Exploitation Surface Securing Skill Templates Against Malicious Inputs There’s a familiar lie in engineering: it’s just a wrapper . Just a thin layer over a shell command. Just a convenience script. Just a little skill template that saves time. That lie ages badly. The moment a CLI tool starts accepting dynamic input from prompts, templates, files, issue text, documentation, emails, or model-generated content, it stops being “just a wrapper” and becomes an exploitation surface. Same shell. Same filesystem. Same credentials. New attack path. This is where teams get sloppy. They see automation and assume efficiency. Attackers see trust transitivity and start sharpening knives. The Real Problem Isn’t the CLI The shell is not new. Unsafe composition is. Most modern automation stacks don’t fail because Bash suddenly became more dangerous. They fail because developers bolt natural language, templates, or tool-chaining onto CLIs without rethinking ...
