Check whether you run silverstripe/graphql (Packagist) or silverstripe/recipe-cms (Packagist) at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.
