Summary: Fides Server-Side Request Forgery Vulnerability in Custom Integration Upload

Details: ### 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.
