Drupal core - Moderately critical - Access Bypass - SA-CORE-2021-010
Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled are not affected. This advisory is not covered by Drupal Steward.
