Summary

Drupal S3 File System versions from 0.0.0 before 3.12.0 assign incorrect permissions to a critical resource (CWE-732), which lets attackers bypass access controls. The flaw stems from incorrectly configured access control security levels. A remote attacker with no privileges and no user interaction can gain access that should be restricted, with low impact to confidentiality, integrity and availability.
