pyLoad: Server-Side Request Forgery via Download Link Submission Enables Cloud Metadata Exfiltration

Published Mar 27, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
pyLoad is a free and open-source download manager written in Python. Prior to version 0.5.0b3.dev97, PyLoad's download engine accepts arbitrary URLs without validation, enabling Server-Side Request Forgery (SSRF) attacks. An authenticated attacker can exploit this to access internal network services and exfiltrate cloud provider metadata. On DigitalOcean droplets, this exposes sensitive infrastructure data including droplet ID, network configuration, region, authentication keys, and SSH keys configured in user-data/cloud-init. Version 0.5.0b3.dev97 contains a patch.
