Drupal core – Moderately critical – Access bypass – SA-CORE-2022-009

Read Time:51 Second
Project: 
Date: 
2022-April-20
Vulnerability: 
Access bypass
Description: 

Drupal 9.3 implemented a generic entity access API for entity revisions. However, this API was not completely integrated with existing permissions, resulting in some possible access bypass for users who have access to use revisions of content generally, but who do not have access to individual items of node and media content.

This vulnerability only affects sites using Drupal’s revision system.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.3, update to Drupal 9.3.12.

All releases prior to Drupal 9.3 (including Drupal 7) are not affected.

Drupal core – Moderately critical – Improper input validation – SA-CORE-2022-008

Read Time:1 Minute, 3 Second
Project: 
Date: 
2022-April-20
Vulnerability: 
Improper input validation
Description: 

Drupal core’s form API has a vulnerability where certain contributed or custom modules’ forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data.

We do not know of affected forms within core itself, but contributed and custom project forms could be affected. Installing this update will fix those forms.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.3, update to Drupal 9.3.12.
If you are using Drupal 9.2, update to Drupal 9.2.18.

All versions of Drupal 9 prior to 9.2.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 is not affected.
