Malcolm 的文件上传组件在很大程度上未经修改地使用了上游的 FilePond PHP 服务器（pqina/filepond-server-php）：Dockerfile 会复制上游所有的 *.php 文件，而 Malcolm 仅覆盖 config.php 和 submit.php。上游的 index.php 暴露了一个获取 API 路由，该路由指示服务器使用 curl（包括 FOLLOWLOCATION 选项）下载任意 URL，并且对于 HEAD 请求，会将获取到的响应体存储在上传容器的传输目录中，并将传输

Vulnerability Title
Server-Side Request Forgery in Malcolm
Source: CVE Program / CVE List V5
Vulnerability 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.
