If enabled, CSP has significant impact on the way browsers render pages (e.g., inline JavaScript is disabled by default and must be explicitly allowed in the policy). CSP prevents a wide range of attacks, including cross-site scripting and other cross-site injections.

Expected result:

"Content-Security-Policy" => "default-src 'self'; img-src 'self' data: https://vcsa.vmware.com; font-src 'self' data:; object-src 'none'; style-src 'self' 'unsafe-inline'",

If the output does not match the expected result, this is a finding.
