Using Appcues with Content Security Policy

Appcues is a product adoption tool. CSP integration is straightforward, but notice that they require adding res.cloudinary.com (which is essentially an open CDN), twemoji, and have Google fonts as a dependency.

Allow these directives in your CSP, to support Appcues in your Content Security Policy:

script-src
  https://fast.appcues.com
  https://fast.appcues.net;
style-src
  *.appcues.com
  *.appcues.net
  fonts.googleapis.com;
frame-src
  *.appcues.com;
img-src
  res.cloudinary.com
  twemoji.maxcdn.com;
connect-src
  *.appcues.com
  *.appcues.net
  wss://*.appcues.net
  wss://*.appcues.com;

The main domains used by Appcues are:

appcues.com
appcues.net

Example Content-Security-Policy violations / reports:

Using the above CSP package, will fix these errors that you may be seeing in your console logs:

script-src/script-src-elem/script-src-attrviolations

Refused to load the script 'https://fast.appcues.com/*.js' because it violates the following Content Security Policy directive: "script-src 'self' 'report-sample'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.

If you see inline style errors, you need to add SHA-256 hashes / nonces to your CSP with RapidSec:

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'report-sample'". Either the 'unsafe-inline' keyword, a hash ('sha256-RFWPLDbv2BY+rCkDzsE+0fr8ylGr2R2faWMhq4lfEQc='), or a nonce ('nonce-...') is required to enable inline execution.

If you see inline eval() errors, RapidSec will generate your CSP with the specific content of the errors:

Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'report-sample'".

style-src/style-src-elem/style-src-attrviolations

Refused to load the stylesheet 'https://fast.appcues.com/generic/main/*/*.css' because it violates the following Content Security Policy directive: "style-src 'self' 'report-sample'". Note that 'style-src-elem' was not explicitly set, so 'style-src' is used as a fallback.

If you see inline style errors, you need to add SHA-256 hashes / nonces to your CSP with RapidSec:

Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self' 'report-sample'". Either the 'unsafe-inline' keyword, a hash ('sha256-RFWPLDbv2BY+rCkDzsE+0fr8ylGr2R2faWMhq4lfEQc='), or a nonce ('nonce-...') is required to enable inline execution.
