What is CVE-2026-35412?

Directus, a real-time API and dashboard application for managing SQL database content, has a vulnerability within its TUS resumable upload feature. Prior to version 11.16.1, this vulnerability allows any authenticated user with basic file upload permissions to overwrite arbitrary existing files using their UUID. The TUS controller only performs collection-level authorization checks without verifying item-level access for the specific files being replaced. Consequently, users can bypass row-level permission rules, allowing unauthorized updates to files they do not own. This poses a significant risk to data integrity and confidentiality, which is addressed in the release of version 11.16.1.
