Authentication bypass in SilverStripe GraphQL

  • Disclosed: 10.06.2021
  • Updated: 11.10.2026 10:22

The GraphQL module accepts basic-auth as an authentication method by default. This can be used to bypass MFA authentication if the silverstripe/mfa module is installed, which is now a commonly installed module. A users password is still required though.

Basic-auth has been removed as a default authentication method. If desired, it can be re-enabled by adding it to the authenticators key of a schema, or on SilverStripe\Graphql\Auth\Handler
