W013: Attempt to modify system services in skill instructions
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
Attempt to modify system services in skill instructions detected (high risk: 1.00). This skill explicitly instructs the agent to perform privileged, state-changing operations (install updates/packages, enable unattended-upgrades, configure UFW/fail2ban, modify SSH/root and sudo settings) on target servers, actions that require sudo and can modify the machine's state.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill runs SSH commands against arbitrary user-supplied hosts (see sshExec/sshExecSafe in index.ts) and parses remote stdout (e.g., /etc/ssh/sshd_config, apt list, systemctl outputs) as part of its audit-and-fix workflow, so untrusted third-party host content can influence decisions and applied actions.
