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://bat.bing.com/bat.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://r.bing.com/rp/*.br.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.
