Description:

Drupal has released a security advisory to address multiple vulnerabilities in the JSON:API, Media, QuickEdit and REST File upload modules.  A remote attacker may upload a maliciously crafted file to a vulnerable system or entice a system administrator into opening a specially crafted web page to exploit the vulnerability.

Please note that Drupal 8 prior to version 8.9.x and Drupal 9 prior to version 9.1.x have reached End-Of-Life (EOL).  No security updates will be provided after that.  Users should arrange upgrading the Drupal to supported versions or migrating to other supported technology.

Affected Systems:

• Drupal version 8.9.x
• Drupal version 9.1.x
• Drupal version 9.2.x

Impact:

Successful exploitation could lead to cross-site scripting, information disclosure or security restriction bypass on an affected system.

Recommendation:

The product vendor has released patches to address the issues.
