Content Security Policy

The Content Security Policy (CSP) feature mitigates a broad class of content injection vulnerabilities, such as cross-site scripting (XSS), by providing policy directives to compliant browsers. This feature is enabled by default. You can reconfigure the policy directives by adding entries to locked.properties.

You can add CSP properties to the locked.properties file. Example CSP properties:

enableCSP = true
content-security-policy = default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self'
 'unsafe-inline';font-src 'self' data:
content-security-policy-newadmin = default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self'
