CVE-2020-13677: Drupal core access bypass vulnerability

February 12, 2022 (updated October 4, 2023)

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.
