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.
Install the latest version:
- If you are using Drupal 9.2, update to Drupal 9.2.6.
- If you are using Drupal 9.1, update to Drupal 9.1.13.
- If you are using Drupal 8.9, update to Drupal 8.9.19.
Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
Drupal 7 core does not include the JSON:API module and therefore is not affected.
