You can install this module separately as helmet-csp. Sets all of the defaults, but overrides `script-src` and disables the default `style-src` app. You can also get the default directives object with (). When an application begins to run, RASP can protect it from malicious input or behavior by analyzing both the apps behavior and the context of that behavior. If you want to set both the normal and Report-Only headers, see this code snippet. If true, the Content-Security-Policy-Report-Only header will be set instead. Options.reportOnly is a boolean, defaulting to false.

Here is the default policy (whitespace added for readability): default-src 'self' These directives are merged into a default policy, which you can disable by setting eDefaults to false. The default-src can be explicitly disabled by setting its value to. If a function appears in the iterable, it will be called with the request and response. Each value is an iterable (usually an array) of strings or functions for that directive. Each key is a directive name in camel case (such as defaultSrc) or kebab case (such as default-src). You should rely on CSP checkers like CSP Evaluator instead. This middleware performs very little validation. See MDN's introductory article on Content Security Policy. ntentSecurityPolicy sets the Content-Security-Policy header which helps mitigate cross-site scripting attacks, among other things. Content-Security-Policy: default-src 'self' base-uri 'self' font-src 'self' https: data: form-action 'self' frame-ancestors 'self' img-src 'self' data: object-src 'none' script-src 'self' script-src-attr 'none' style-src 'self' https: 'unsafe-inline' upgrade-insecure-requests
