CVE-2020-26136
MEDIUM6.5EPSS 0.22%Authentication bypass in SilverStripe GraphQL
Published: 6/10/2021Modified: 2/17/2024
Description
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
