DRUPAL-CORE-2023-005
No affected components available
The file download facility doesn't sufficiently sanitize file paths in certain situations. This may result in users gaining access to private files that they should not have access to.
Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing private files after updating.
This advisory is covered by Drupal Steward. Because this vulnerability is not mass exploitable, your Steward partner may respond by monitoring-only, rather than enforcing a new WAF rule.
We would normally not apply for a release of this severity. However, in this case we have chosen to apply Drupal Steward security coverage to test our processes.
