Reports are still accessible even when `canView()` returns false in silverstripe/reports
silverstripe/reports is an API for creating backend reports in the Silverstripe Framework. In affected versions reports can be accessed by their direct URL by any user who has access to view the reports admin section, even if the `canView()` method for that report returns `false`. This issue has been addressed in version 5.2.3. All users are advised to upgrade. There are no known workarounds for this vulnerability.
