🛡️ Content Security Policy in TYPO3
Content Security Policy (CSP) is a security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting of malicious content being executed in the trusted web page context.
I have no patience for dealing with the #RubyOnRails core team, but if •you• do, then…
It would be super if it were possible to append values to the #ContentSecurityPolicy configuration. For example:
```ruby
Rails.application.configure do
config.content_security_policy do |policy|
policy.script_src :self, :https
if Rails.env.development?
policy.script_src << :unsafe_inline
end
end
end
```

Des experts en #ContentSecurityPolicy ?
Pour mon site, j'ai :
<meta http-equiv="Content-Security-Policy" content="default-src https: data: 'unsafe-eval' 'unsafe-inline'; object-src 'none'">
Mozilla Observatory me dit :
Remove unsafe-inline and data: from script-src, overly broad sources from object-src and script-src, and ensure object-src and script-src are set.
Et si je mets :
Content-Security-Policy: default-src 'self';
ça casse mon site, mais je ne vois pas pourquoi. Quelqu'un saurait me dire ce qu'il me faut écrire, les ressources étant toutes sur mon site ?
Merci :)
Apropos of nothing, can anyone recommend any services that aggregate CSP policy reports that are suitable for hobby websites? (i.e. are free, because I just want to do the right thing where I can, and don't care enough to pay for it because it's not vital to operations)

Excellent. I figured out why Mastodon didn't work on Firefox. Apparently ANY tool that either changes the format of the webpage (disables javascript) including things that change the format (css) can cause catastrophe.
The solution for me was adding all mastodon-type pages to the black-list for 'bionic reader'.
Today in ridiculous Web browser bugs:
Setting up CSP headers closer to the client helps - setting up CSP headers as meta tags inside the index.html. This is protecting your website as early in the process as possible.
@qubyte I've written down my experience in a blog post and created a sample repository https://lennybacon.com/posts/jsmodulesimportmapsandcontentsecuritypolicy/

Our first #OpenSource release since our company was legally constituted. Not a big deal, but sort of a milestone :D.

This is a great article to familiarize yourself with the Content Security Policy (#CSP) security concept. Many thanks to #b13 for sharing the well-founded information. #TYPO3 #CyberSecurity #ContentSecurityPolicy

Implementing a halfway decent #contentsecuritypolicy is like herding cats.
The sheer number of random domains that third party services use is insane.
It's 2024 and modern #javascript libraries still need you to allow unsafe-eval in your #contentsecuritypolicy :(
i'm annoyed that a good #contentSecurityPolicy doesn't let me just dump raw #javascript into #html anymore. that was really convenient.
Wie baue ich eine Content Security Policy (CSP) die nicht die ganze Webseite kaputt macht? :D

Today I learned about Google's CSP evaluator.
Feed it a Content Security Policy or a link to a website where it can infer one, and it will evaluate it.
