Security Findings1
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Potential for Command Injection via tmux commands The skill describes and provides examples for executing `tmux` commands such as `tmux new-session` and `tmux send-keys`. These commands are designed to execute arbitrary shell commands or send keystrokes to a shell within a `tmux` session. If an AI agent constructs the session name (`<name>`) or the command string (`<command>`) from untrusted user input without proper sanitization, it could lead to arbitrary command execution on the host system. For instance, injecting shell metacharacters into the session name or the command string could allow an attacker to run unintended commands outside the `tmux` context or within the `tmux` session, leading to system compromise or data exfiltration. Implement robust input validation and sanitization for any parameters derived from untrusted sources (e.g., user input) before constructing `tmux` commands. Ensure that session names and commands sent via `send-keys` are properly escaped or restricted to a safe set of characters. Consider using a dedicated `tmux` client library that handles escaping, if available, or strictly whitelist allowed commands/arguments to prevent injection. | LLM | SKILL.md:30 |
