Directus is a real-time API and App dashboard for managing SQL database content. The `@directus/storage-driver-s3` package starting in version 9.22.0 and prior to version 12.0.1, corresponding to Directus starting in version 9.22.0 and prior to 11.5.0, is vulnerable to asset unavailability after a burst of HEAD requests. Some tools use Directus to sync content and assets, and some of those tools use the HEAD method to check the existence of files. When making many HEAD requests at once, at some point, all assets are eventually served as 403. This causes denial of assets for all policies of Directus, including Admin and Public. Version 12.0.1 of the `@directus/storage-driver-s3` package, corresponding to version 11.5.0 of Directus, fixes the issue.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
