Malcolm FilePond Server Arbitrary File Download

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: ICS-CERT

Description
Malcolm file-upload component ships the upstream FilePond PHP server (pqina/filepond-server-php) largely unmodified: Dockerfile copies all upstream *.php files and Malcolm only overwrites config.php and submit.php. Upstream index.php exposes a fetch API route that instructs the server to download an arbitrary URL with curl (including FOLLOWLOCATION) and, for HEAD requests, stores the fetched response body in the upload container's transfer directory and returns the transfer ID to the caller, enabling full readback of the fetched content.

Executive Summary

This vulnerability involves the Malcolm file-upload component using an upstream FilePond PHP server with minimal modifications. The index.php file exposes an API route that uses curl to download arbitrary URLs, including following redirects. For HEAD requests, it stores the fetched response body in a transfer directory and returns a transfer ID, allowing full readback of the fetched content.

Impact Analysis

An attacker could exploit this to read sensitive files or data from internal systems by tricking the server into fetching and exposing their contents. This could lead to unauthorized access to confidential information, data breaches, or further network infiltration.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Disable or restrict access to the FilePond PHP server's fetch API route that allows arbitrary URL downloads. Update Malcolm to a patched version if available. Monitor network traffic for unusual outbound connections from the upload container.
