CVE Published:

Summary

When users attempt to add a private file through the editor in versions of Drupal 8.2.x prior to 8.2.7, the access control checks for the attached file are not enforced correctly. This weakness allows unauthorized users to bypass restrictions and potentially gain access to sensitive files, leading to unauthorized data exposure. It is crucial for administrators to upgrade to the patched version to mitigate the risk of exploitation and ensure that proper access controls are enforced.

Affected Version(s)

Drupal Core 8.2.x versions before 8.2.7
