Analyse de sécurité
PrudenceThe skill runs a Bun script with a user-supplied URL as argument in a Bash environment. If the agent does not properly quote the URL, shell metacharacters (e.g., ;, &&, |) could lead to unintended command execution. The script itself appears safe, but the lack of guidance on input handling introduces risk.
- •URL argument passed to shell command without explicit quoting or sanitization, potentially allowing command injection if user input contains shell metacharacters.
