Fides Server-Side Request Forgery Vulnerability in Custom Integration Upload

Impact

The Fides web application allows a custom integration to be uploaded as a ZIP file containing configuration and dataset definitions in YAML format.

It was discovered that specially crafted YAML dataset and config files allow a malicious user to perform arbitrary requests to internal systems and exfiltrate data outside the environment (also known as a Server-Side Request Forgery). The application does not perform proper validation to block attempts to connect to internal (including localhost) resources.

Exploitation is limited to API clients with the CONNECTOR_TEMPLATE_REGISTER authorization scope. In the Fides Admin UI this scope is restricted to highly privileged users, specifically root users and users with the owner role.

Patches

The vulnerability has been patched in Fides version 2.22.1. Users are advised to upgrade to this version or later to secure their systems against this threat.

Workarounds

There are no workarounds.
