CVE-2026-33992 Details
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.
A Server-Side Request Forgery (SSRF) vulnerability has been identified in pyLoad versions prior to 0.5.0b3.dev97. The issue arises because the download engine accepts arbitrary URLs without proper validation. This flaw allows authenticated attackers to access internal network services and exfiltrate sensitive cloud provider metadata. On DigitalOcean droplets, this vulnerability could lead to the exposure of critical infrastructure data, including droplet ID, network configuration, region, authentication keys, and SSH keys stored in user-data or cloud-init.
Users are advised to update to pyLoad version 0.5.0b3.dev97, which includes a patch for this vulnerability. Additionally, implement URL validation in the download engine to whitelist allowed URL schemes, block requests to private IP ranges and cloud metadata endpoints, and validate request destinations before initiating downloads.
