Description Preview
The Drupal core JSON:API module contains a security vulnerability that under certain circumstances fails to properly restrict access to content, potentially allowing unauthorized users to access restricted information. This vulnerability only affects sites that have the JSON:API module enabled.
Overview
CVE-2020-13677 is an access bypass vulnerability in Drupal's core JSON:API module. The issue occurs because the module does not properly implement access restrictions in some scenarios, which could allow attackers to bypass intended security controls and gain access to content they should not be able to view. This vulnerability could lead to information disclosure of sensitive data that should be protected by Drupal's permission system. The vulnerability is particularly concerning for sites that use the JSON:API module to expose content via APIs while expecting Drupal's permission system to protect sensitive information.
Remediation
To remediate this vulnerability, site administrators should:
- Update to the latest secure version of Drupal as specified in the security advisory (SA-CORE-2021-010)
- For Drupal 9, update to version 9.1.15, 9.2.10, or 9.3.0 or later
- For Drupal 8, update to version 8.9.19 or later
- If immediate updating is not possible, consider temporarily disabling the JSON:API module until updates can be applied
- After updating, review access logs for any signs of exploitation
- Ensure that your site's permission configuration is correctly set up to minimize potential impact
