🔴 VERDICT: CRITICAL

The lighthouse-runner.sh script executes the Lighthouse CLI with the --no-sandbox flag for Chrome. This flag disables a critical security feature of the browser. When combined with the skill's ability to accept an arbitrary URL from the user, this creates a severe vulnerability. If a user provides a URL to a malicious website that exploits a browser vulnerability, the --no-sandbox flag would allow the exploit to escape the browser's sandbox and potentially execute arbitrary code on the host system, leading to full system compromise.

Total Findings: 2

🔴 CRITICAL Findings: • Privilege Escalation / Command Execution (via --no-sandbox)

• scripts/lighthouse-runner.sh:100: lighthouse "$URL" "${LH_FLAGS[@]}" The script runs lighthouse with --chrome-flags=--headless --no-sandbox --disable-gpu. The --no-sandbox flag is a critical security risk, as it removes a primary defense mechanism of the browser. If the user-provided URL points to a malicious web page, a browser exploit could escape the browser's process and compromise the host system.

ℹ️ TRUSTED SOURCE References: • External Dependency (Lighthouse CLI)

• SKILL.md:20: npm install -g lighthouse The skill instructs the user to install lighthouse globally via npm. Lighthouse is a well-known project maintained by Google, a trusted organization. This is noted as an informational finding because it's an external dependency, but its trusted source status downgrades the severity of this specific finding.
