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.
