CVE-2026-39942 is a high-severity flaw (CVSS 8.5) affecting directus. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, the PATCH /files/{id} endpoint accepts a user-controlled filename_disk parameter. By setting this value to match the storage path of another user's file, an attacker can overwrite that file's content while manipulating metadata fields such as uploaded_by to obscure the tampering. This vulnerability is fixed in 11.17.0.
