CVE-2025-30350
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDirectus 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application allocates memory, connections, or handles in response to a request without enforcing any cap, so a modest amount of malicious traffic exhausts the resource and denies service to everyone else. The fix is enforcing quotas, limits, and timeouts on what any single request or client can consume.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped11.5.0
Directus 11.5.0 (includes @directus/[email protected])
- Back up your Directus database and all files before upgrading
- Upgrade Directus to version 11.5.0, which includes the patched @directus/storage-driver-s3 version 12.0.1
- After upgrading, clear any cache and restart the Directus application
- Verify that HEAD requests no longer cause 403 errors on assets by testing with multiple concurrent HEAD requests
