CVE-2020-13665
CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Drupal Core versions prior to 8.8.8
Drupal Core versions prior to 8.9.1
Drupal Core versions prior to 9.0.1
Description
The issue is related to improper authorization in the Drupal Core JSON:API module when the read only setting is set to FALSE. This can allow a remote attacker to access sensitive data, compromise data integrity, and potentially cause a denial of service. The vulnerability affects sites with JSON:API in read/write mode.
Recommendations
For versions prior to 8.8.8, update to version 8.8.8 or later.
For versions prior to 8.9.1, update to version 8.9.1 or later.
For versions prior to 9.0.1, update to version 9.0.1 or later.
As a temporary workaround, consider setting the read only setting to TRUE under jsonapi.settings config to prevent exploitation.
