CVE-2026-107362: Malcolm file-upload component SSRF via FilePond fetch API

CVE-2026-107362 · Severity: high · CVSS 7.1 · Published 2026-10-08

How to fix

Fixed in: v26.09.0

Technical details

The bundled FilePond PHP server's index.php exposes a fetch API route that accepts arbitrary URLs and uses curl with FOLLOWLOCATION enabled to retrieve them, storing response bodies in an accessible transfer directory. An authenticated user can exploit this server-side request forgery (SSRF) via HEAD requests to read HTTP, HTTPS, or FTP responses from internal services (OpenSearch, Malcolm API, Dashboards, NetBox, Valkey, and Docker gateway-reachable hosts), then retrieve stored bodies via the restore endpoint. The fix ships in v26.09.0 by removing the fetch route handler entirely.
