Upstream source description

### Impact The CSRF authenticity token check is currently disabled for the questionnaire templates preview as per: https://github.com/decidim/decidim/blob/3187bdfd40ea1c57c2c12512b09a7fec0b2bed08/decidim-templates/app/controllers/decidim/templates/admin/questionnaire_templates_controller.rb#L11 This was introduced by this commit in the PR that introduced this feature (#6247): https://github.com/decidim/decidim/pull/6247/commits/5542227be66e3b6d7530f5b536069bce09376660 The issue does not imply a serious security thread as you need to have access also to the session cookie in order to see this resource. This URL does not allow modifying the resource but it may allow attackers to gain access to information which was not meant to be public. ### Patches #11743 ### Workarounds Disable the templates functionality or remove all available templates. ### References #11743
