Behavioral Risk Signals
Security Findings1
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Potential Command Injection via Host Argument The skill's documentation describes a command-line interface `ping-monitor <host>` that takes a host as an argument. The manifest confirms the skill requires the `ping` binary. If the user-provided `<host>` input is directly incorporated into a shell command without proper sanitization or escaping, it could lead to command injection. An attacker could provide input like `8.8.8.8; cat /etc/passwd` to execute arbitrary commands on the system. Implement robust input validation and sanitization for all user-provided arguments, especially the `<host>` parameter. When executing external commands, use safe subprocess execution methods (e.g., `subprocess.run` with `shell=False` and passing arguments as a list) instead of constructing shell command strings directly. | LLM | SKILL.md:9 |
