CVE-2026-39942: Monospace Directus

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Monospace Directus: before 11.17.0 (fixed in 11.17.0)
