Content Security Policy Manager is a WordPress plugin that allows you to easily configure Content Security Policy headers for your site. You can have different CSP headers for the admin interface, the frontend for logged in users, and the frontend for regular visitors. The CSP directives can be individually enabled, and each policy can be set to enforce, report or be disabled.
Please note that this plugin offers limited help in figuring out what the contents of the policy should be. It only lets you configure the CSP in a easy to use interface.
Hello,
Since report-uri is no longer recommended anymore, I need to use report-to to send CSP reports. But for reason, it doesn’t send reports with report-to. My CSP settings are as follows:
In Policy: report-to filed, I filled in csp-endpoint , in Frontend Policy Report-To Header field, I filled in the following JSON data
{
"group": "csp-endpoint",
"max_age": 10886400,
"endpoints": [
{
"url": "{CSP REPORT ENDPOINT}"
}
]
}
After saving changes in the CMS, all the commas disappeared in Frontend Policy Report-To Header field.
{ "group": "csp-endpoint" "max_age": 10886400 "endpoints": [ { "url": "{CSP REPORT ENDPOINT}" } ] }
I am wondering if you can help to take a look at it, thanks! Note: I have no problem with report-uri.
As soon as I leave the backend the view of my side is without any CSS. Only the plain HTML.
We are really happy with this plugin.
im wondering if you provide a filter so i can merge some dynamic ‘nonce-xx’ to the policy header. this could be very very useful.
This plugin is well thought out and does what I need it to. It has also helped me troubleshoot other website’s CSP that wasn’t working correctly, and the documentation is solid if brief.
Ce plugin m;a fait gagner des heures de travail.
