Adds CSP headers to your request, based on configuration in a yml file.

Setting up a report-uri account is free and easy

Disclaimer

If this module breaks your website, you get to keep all the pieces.

Requirements

SilverStripe Framework 4.x+ PHP 8.0+

Installation

composer require firesphere/cspheaders

Configuration and usage

See the documentation

WARNING

When using this module and have CSS hashes or nonces enabled, any inline styles declared on HTML Elements themselves will not work anymore.

To enable or disable inline javascripts or css, set the appropriate flag (allow-inline) in your yml config.

Same goes for javascripts. Javascripts specifically should live either in a separate file, or be added using Requirementns::customScripts()

Default for css is therefore false, javascript however defaults to true for security reasons.

CDN Providers

When using Incapsula or Imperva (and potentially other CDN providers), your CSS and JavaScripts may be altered by the CDN, and therefore never compute correctly.

The only solution is to disable the SRI's for css and javascript on these providers.

.htaccess

Any header set in the .htaccess, Apache site.conf or nginx.conf files will override the headers set by this module.
