CVE-2026-35412 Details
Description
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.16.1, Directus' TUS resumable upload endpoint (/files/tus) allows any authenticated user with basic file upload permissions to overwrite arbitrary existing files by UUID. The TUS controller performs only collection-level authorization checks, verifying the user has some permission on directus_files, but never validates item-level access to the specific file being replaced. As a result, row-level permission rules (e.g., "users can only update their own files") are completely bypassed via the TUS path while being correctly enforced on the standard REST upload path. This vulnerability is fixed in 11.16.1.
A vulnerability in Directus prior to version 11.16.1 allows authenticated users with basic file upload permissions to overwrite arbitrary existing files through the TUS resumable upload endpoint. The issue arises because the TUS controller only performs collection-level authorization checks, ensuring the user has some permission on 'directus_files', but fails to validate item-level access to the specific file being replaced. This oversight allows users to bypass row-level permission rules, such as restrictions on updating personal files, while these rules are properly enforced on the standard REST upload path.
Users can disable TUS uploads by setting 'TUS_ENABLED=false' if resumable uploads are not needed.
