Aliases CVE-2017-6928
GHSA-66mv-q8r2-hj8w
Summary Incorrect Permission Assignment for Critical Resource When using Drupal's private file system, Drupal will check to make sure a user has access to a file before allowing the user to view or download it. This check fails under certain conditions in which one module is trying to grant access to the file and another is trying to deny it, leading to an access bypass vulnerability. This vulnerability is mitigated by the fact that it only occurs for unusual site configurations.
