Risk Level: HIGHCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
- [COMMAND_EXECUTION]: The
scripts/spawn-worker.shscript is vulnerable to command injection. It constructs a shell command string fortmux split-windowusing single quotes to wrap the$worktree_pathvariable. If the path contains a single quote followed by shell metacharacters, it allows for arbitrary command execution on the host system. Evidence:"cd '$worktree_path' && $claude_cmd". - [COMMAND_EXECUTION]: The skill programmatically bypasses the 'trust' security prompt in the child agent sessions it creates. It uses
tmux capture-paneto detect the trust request and automatically sends anEnterkey to accept it without user oversight. This defeats a core safety mechanism intended to prevent unauthorized filesystem access. Evidence:if echo "$content" | grep -qi "trust"; then tmux send-keys -t "$pane_id" Enter .... - [INDIRECT_PROMPT_INJECTION]: The skill has a significant attack surface for indirect prompt injection.
- Ingestion points: GitHub issue content is retrieved via
gh issue viewand passed directly as instructions to newly spawned agents inSKILL.md. - Boundary markers: The child agents are started in
planmode, which provides some oversight, but the skill's automated trust bypass reduces the user's ability to intervene before the agent acts. - Capability inventory: Child agents possess full filesystem access, network capabilities, and the ability to execute code within the repository worktree.
- Sanitization: There is no evidence of sanitization or escaping of the issue title or description before it is passed as a primary instruction to the worker agent.
