HTTP CSRF Protection - Middleware (PSR15)
PSR15 Middleware to protect your application againts Cross-Site Request Forgery
This middleware use the Cookies to store a token used for comparaison in each "unsafe" request (POST
/PUT
/PATCH
/DELETE
).
Why?
Because.
Installation
To activate the extension:
The extension will activate Chiron\Csrf\Middleware\CsrfTokenMiddleware
to issue a unique token for every user request.
Enable Protection - Specific Route
The extension provides a middleware CsrfProtectionMiddleware
which activates the protection on your routes (specific route or every routes).
This middleware will protect all the requests for the "unsafe" methods POST
, PUT
, PATCH
, DELETE
.
Enable Protection - All Routes
To activate CSRF protection on all the routes, you need to "globally" register Chiron\Csrf\Middleware\CsrfProtectionMiddleware
via MiddlewareQueue
:
Usage
Once the protection is activated, you must sign every request with the token available via PSR-7 attribute csrfToken
.
To receive this token in the controller or view:
Every POST
/PUT
/PATCH
/DELETE
request from the user must include this token as POST parameter csrf-token
or header X-CSRF-Token
.
Users will receive an error 403 Forbidden
if a token is missing.
Users will receive an error 412 Precondition Failed
if the token has been tampered (and the cookie will be deleted).
TODO
- Add documentation on the "csrf_token()" helper.
- Create a TwigExtension class to add the csrf_token.
