Test failure.

Sorry, I can see the all tests passed. Which tests failed?

Left some feedback on the MR.

Rerolled patch for D10.1.x

Can confirm #128 applies cleanly and works on Drupal 10.1.6

This needs an MR against 11.x at this point.

It's possible to remove the CSRF check by using a directive set to the modulename.routing.yml file

see how this dropzonejs patch is doing it:
#3197207-02: Anonymous users cannot upload caused by invalid csrf-token →

This patch is for 10.3.x version

How does this committed issue 🐛 User logout is vulnerable to CSRF Fixed and the change record https://www.drupal.org/node/2822514 → affect this issue, 🐛 CSRF check always fails for users without a session Needs work ?

Leaving as needs work.

#132 failed to apply for me on 10.3.0. Re-rolled against branch 10.3.x

A new patch for Drupal Core 10.3.7 was generated from 2730351-D10.3.x-134 patch

The patch #135 stopped working after updating to 10.4.2

confirm #136 - patch #135 works until 10.4.1, stopped working with 10.4.2

couldn't apply the MR diff either, so I'm stuck at 10.4.1 for the given project :(

A new patch for Drupal Core 10.4.2 was generated from drupal-core-10.3.7-2730351-135.patch

@sabrina.liman Please do not change the version or the category. Core development is currently on 11.x.

@sabrina.liman , patches are no longer preferred, please use existing MR to contribute or create a different MR if you have an alternative solution than the existing one.

Patch #141 also doesn't work since it has a critical issue: Uncaught PHP Exception Error: "Call to a member function hasSession() on null" at /core/lib/Drupal/Core/Access/RouteProcessorCsrf.php line 44

I understand MR is better, but I didn't have enough time to do that.
