Thanks for the PR 😍

How to test these changes in your application

Define the SYMFONY_ENDPOINT environment variable:

# On Unix-like (BSD, Linux and macOS)
export SYMFONY_ENDPOINT=https://raw.githubusercontent.com/symfony/recipes/flex/pull-1337/index.json
# On Windows
SET SYMFONY_ENDPOINT=https://raw.githubusercontent.com/symfony/recipes/flex/pull-1337/index.json

Install the package(s) related to this recipe:

composer req 'symfony/flex:^1.16'
composer req 'symfony/framework-bundle:^7.2' 'symfony/stimulus-bundle:^2.19' 'symfony/ux-turbo:^2.19'

Don't forget to unset the SYMFONY_ENDPOINT environment variable when done:

# On Unix-like (BSD, Linux and macOS)
unset SYMFONY_ENDPOINT
# On Windows
SET SYMFONY_ENDPOINT=

Diff between recipe versions

In order to help with the review stage, I'm in charge of computing the diff between the various versions of patched recipes.
I'm going keep this comment up to date with any updates of the attached patch.

should we enable this double-submit validation by default ? For sites that rely on stateful authentication anyway, the session-based CSRF token manager has the benefit of being compatible with form submissions done without JS (either because JS is disabled or because it failed to execute)

+document.addEventListener('submit', function (event) {


IMO, it would make sense to ship this controller in a symfony/ux package instead of a recipe, so that it can be properly maintained (for instance, there is no good way to manage security advisories for code provided by recipes, because the advisories would have to apply to projects that were created based on the recipe, not on the recipe itself, as the recipe is not a dependency of the project).

Then, we could have the recipe of that bundle turning on the double-submit CSRF protection.

I'm not sure we should take control of that snippet. By putting it in client's app, we make it easy to tweak. But moving it to vendor dep would require making it parametrized, and this is a path we'd better not take IMHO.
If we have to change the script for security reasons, we can always use another data-contoller attribute by default so that older versions become dead-code.

We're trying to slim down the number of ux packages to only include ones that have a decent amount of both PHP and JS. Our long(ish)-term plan is to create a sort of recipe system on ux.symfony.com where user's could copy paste code (stimulus controllers, twig components, etc) into their apps. Several of our existing ux packages would then be deprecated in favour of a recipe.

Because the snippets are copy/pasted we don't have to worry about breaking apps when we improve the recipes.

That being said, the security situation isn't something I've thought of with regards to this system.

The issue with copy-paste and that the project in which you paste the code has no relation to the place where you copied it, and so security advisory systems cannot copy the advisories they have for the source to all projects in which you pasted the code (not even considering the fact that advisories are about affected versions of each project).

When the code is just glue code, this is fine as this is generally not the source of a security issues (if some particular usages of a library would be insecure, the library itself would have an advisory). But this case is not about glue code but implementing the (security-related) feature itself.

Several of our existing ux packages would then be deprecated in favour of a recipe.

That plan is not needed: keep the packages but turn them into symfony-packs instead, that'll provide the best DX.

About putting that snippet for double-submit, I have the same approach: I don't want to make this a vendor package. I prefer putting people in charge.

The security aspect of this is very limited. The server-side is in control of what it accepts.

should we enable this double-submit validation by default ? For sites that rely on stateful authentication anyway, the session-based CSRF token manager has the benefit of being compatible with form submissions done without JS (either because JS is disabled or because it failed to execute)

We should yes IMHO. Submissions done without JS are also compatible thanks to the Origin check, which is enough to accept the submission. The cookie submission becomes required only if a previous submission successfully used it (which means JS was enabled before). The only thing this would break is support for legacy browsers that don't send neither origin nor have JS enabled. Given we're talking about new projects here, that's acceptable (and it's still possible to reconfigure so everybody is covered, advanced users should do some more work as expected, but the DX is best by default.)

Do i understand this wrong or ... will it fail for every form where Turbo is not enabled ?

Because this is a very common scenario

you've got it right - new projects start with turbo enabled for every forms

Ok.. bold but we'll see :) And worst case a PR is quickly done to add an option :)

I think we need to link to a documentation page here what this means with pros and cons. It's not very self-explaning.

This makes every form use the same token ID from what I understand. But this is in constrast to the recommendation at https://symfony.com/doc/current/security/csrf.html#csrf-protection-in-symfony-forms

// an arbitrary string used to generate the value of the token
// using a different string for each form improves its security
'csrf_token_id' => 'task_item',

If that is not true, it should be changed. What's the point of the token ID then at all? Just a way to distinguish different forms?

Thanks for the comments. I agree docs on the topic need to be changed after this PR.
(Yes, token id is to differentiate by use case for each tokens, which means by forms most of the time, but this is not required for the CSRF protection to be effective)
