🚨 Severity: MEDIUM
💡 Vulnerability: The documentation site had a loose Content Security Policy (CSP) and missing security headers. Specifically, it whitelisted unused external font origins, was missing
frame-ancestors 'none', and had a permissivebase-uri.🎯 Impact: Permissive CSPs increase the risk of XSS, clickjacking, and injection attacks. Lack of security headers like
X-Frame-OptionsandX-Content-Type-Optionsweakens the application's defense-in-depth.🔧 Fix:
