Strawberry GraphQL Cross-Site Request Forgery (CSRF) vulnerability

Strawberry GraphQL is a library for creating GraphQL APIs. Prior to version 0.243.0, multipart file upload support as defined in the GraphQL multipart request specification was enabled by default in all Strawberry HTTP view integrations. This made all Strawberry HTTP view integrations vulnerable to cross-site request forgery (CSRF) attacks if users did not explicitly enable CSRF preventing security mechanism for their servers. Additionally, the Django HTTP view integration, in particular, had an exemption for Django's built-in CSRF protection (i.e., the CsrfViewMiddleware middleware) by default. In affect, all Strawberry integrations were vulnerable to CSRF attacks by default. Version v0.243.0 is the first strawberry-graphql including a patch.
