After carefully going over a lot of similar issues I still can't find a solution to this CSP violation error. I am using React with Express backend.
I have tried different Content-Security-Policy meta contents, including giving a full permission string but still getting these two errors.
<meta http-equiv="Content-Security-Policy"
content="
default-src * self blob: data: gap:;
style-src * self 'unsafe-inline' blob: data: gap:;
script-src * 'self' 'unsafe-eval' 'unsafe-inline' blob: data: gap:;
object-src * 'self' blob: data: gap:;
img-src * self 'unsafe-inline' blob: data: gap:;
connect-src self * 'unsafe-inline' blob: data: gap:;
frame-src * self blob: data: gap:;">
Here are the exact error messages:
*Refused to load the script 'https://www.google-analytics.com/analytics.js' because it violates the following Content Security Policy directive: "script-src 'self'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
Refused to load the script 'https://js.stripe.com/v3' because it violates the following Content Security Policy directive: "script-src 'self'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.*
And here is the picture: Error image
How this problem can be tackled? Would appreciate any help.

I have installed GeoServer on my linux machine and is running behind Nginx proxy. GeoServer web interface is working fine. But when I try to create a new store, it is not working. When I click on the "browse" button a modal is opened. That is when the error message is printed on to the console, which says

What to add to my content security policy to get this to work? I have added my domain here as well. But that did not work either.
Here is my CSP:
add_header Content-Security-Policy "base-uri 'self'; default-src 'self'; img-src https 'self' https://amazon-bucket.s3.eu-west-2.amazonaws.com/ data:; object-src 'none'; require-trusted-types-for 'script'; script-src 'unsafe-inline' 'self' https://cdnjs.cloudflare.com https://unpkg.com; style-src 'unsafe-inline' 'self' https://fonts.googleapis.com https://fonts.gstatic.com https://cdnjs.cloudflare.com https://unpkg.com; font-src 'unsafe-inline' 'self' https://cdnjs.cloudflare.com https://fonts.googleapis.com https://fonts.gstatic.com https://unpkg.com";
UPDATE:
I noticed this TrustedHTML assignment error on chrome
This document requires 'TrustedHTML' assignment.
TrustedHTML assignment error
For the first error you'll need to add 'unsafe-eval' to script-src. But note that for each 'unsafe-*' you add the value of your CSP decreases.
TrustedHTML doesn't allow setting innerHTML, use textContent instead if you are setting unformatted text. Otherwise you should be using DOMPurify or some other methods ensure that html is trusted.
I am developing a website with Wordpress that includes a Gumroad script, in the console it throws the following error:

I tried to fix it by putting the info in the meta, but I'm sure I'm wrong.
To fix the issue you have to add https://stats.g.doubleclick.net host-source to connect-src directive.
It's 2 ways to publish CSP:
via meta tag <meta http-equiv="Content-Security-Policy" content="...">
via HTTP header "Content-Security-Policy: ..."
Avoid to use both ways at the same time - in case of 2 CSPs the rules will join with logical "AND" and you'll failed to get expected result.
Therefore you need to know in which way your Wordpress publish the CSP, and then to add the https://stats.g.doubleclick.net into meta OR into HTTP-header respectively.
Typically WP uses plugins to publish CSP. It can also be published in the .htaccess file.
Note 1: the console error you described could be not yours if you use iframe with third-party content (some external widgets, Google auth etc.). Because browser use one console to display CSP violations in any iframes.
Moreover, you could have installed some browsers plugins which tries to modify the viewed page. This can cause CSP violations too.
But lookes like it's caused by Google Adsense you place in web page. `https://stats.g.doubleclick.net. is used to collect stat of Google Ads.
I am setting up a content security policy (CSP)for my website. I have been using it for a few websites for the last weeks without any issue. External scripts and various other things I have successfully integrated.
Today though I wanted to integrate a third part calendar booking system (Calendly). They use an iframe for the popup and for the life of me I can not get it accepted on the security policy.
I keep getting this error
"refused to frame 'url-to-calendly' because it violates the following content security policy directive: "frame-src" ...
I have tired adding this to the frame-src component
frame-src https://assets.calendly.com;
frame-src 'self' https://assets.calendly.com;
frame-src 'self' https://assets.calendly.com 'unsafe-inline';
frame-src https://assets.calendly.com 'nonce-lots-of-digits';
frame-src 'self' https://assets.calendly.com 'nonce-lots-of-digits';
I did the same under the child-src directive as well. Since frame-src is no longer used in version two. Again this did not work either. Here is my full CSP. Any help here would be greatly appreciated - thank you. Ps. I was using chrome dev tools. It appeared to neither work in Safari either.
Content-Security-Policy:
script-src 'nonce-4dfb7738f82d40efc1b73a80491d6dd0bb839173' 'unsafe-inline'; object-src 'none';
default-src 'nonce-77184b203c574dfd8ecc7fac417bf078242d4657';
img-src 'self' https://www.google-analytics.com www.google-analytics.com https://stats.g.doubleclick.net;
style-src 'self' https://assets.calendly.com;
font-src 'self';
connect-src 'self' https://www.google-analytics.com www.google-analytics.com https://stats.g.doubleclick.net;
base-uri 'none';
child-src https://assets.calendly.com;
frame-src https://assets.calendly.com;
To make Calendly work on your website you need to add following CSP rules:
frame-src https://calendly.com;
script-src https://assets.calendly.com;
style-src 'unsafe-inline';
So actually the answer turned out to be very simple. I contacted calendly directly and the simple solution was to change the url I added. https://calendly.com was enough to do the trick.
So the url you gave #andrii was correct - thank you. However using ‘unsafe-inline’ is not advisable. Using that on any of the sources makes your CSP almost pointless having.
You can use like this:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' ;
img-src 'self' 'unsafe-inline'
https://www.google.com/;
style-src 'self' 'unsafe-inline'
https://fonts.googleapis.com ;
script-src 'self' 'unsafe-inline'
https://www.google-analytics.com
https://www.torrentpower.com;
connect-src 'self'
https://google.com/
https://www.google-analytics.com;
child-src 'self' https://www.google.com/;
object-src 'self';">
As part of new security requirement from the client I have added "Content Security Policy" in my Liferay application:
response.setHeader(
"Content-Security-Policy",
"default-src 'none'; script-src 'unsafe-inline' *.googleapis.com; style-src 'self' *.googleapis.com;font-src 'self' *.gstatic.com;connect-src ; img-src 'self' data:;base-uri 'none';frame-ancestors 'none';");
But I am getting below error
Refused to load the script 'http://localhost:8080/o/js_loader_modules?t=1536146336645' because it violates the following Content Security Policy directive: "script-src 'unsafe-inline' *.googleapis.com".
Local server up and running localhost:8080. How to solve this?
It looks like CSP blocks your own script from loading and only allows inline <script> tags from googleapis.com. You should try adding 'self' to your CSP rules, because it means you can use scripts from your own domain.
script-src 'self' 'unsafe-inline' *.googleapis.com;
Hi i have some content security policy like this:
<meta http-equiv="content-security-policy" content="default-src 'self';
script-src 'self' 'nonce-MhqUJrKKq9' https://ajax.googleapis.com/ajax/libs/webfont/1.6.16/webfont.js;
style-src 'self' 'unsafe-inline' https://fonts.googleapis.com/; font-src 'self' https://fonts.gstatic.com/;
object-src 'none'; base-uri 'none';">
I was try to allow a google fonts, but it give me this error:
webfont.js:17 Refused to load the stylesheet 'http://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700%7CRoboto:300,400,500,600,700' because it violates the following Content Security Policy directive: "style-src 'self' 'unsafe-inline' https://fonts.googleapis.com/".
so what can caused this error? i though i already exclude it from my policy.
Try google fonts without https , http://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700%7CRoboto:300,400,500,600,700%27
