CVE-2023-46124 — Ethyca Fides security vulnerability

High CVSS 8.2

Fides is an open-source privacy engineering platform for managing the fulfillment of data privacy requests in runtime environments, and the enforcement of privacy regulations in code. 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. The vulnerability has been patched in Fides version `2.22.1`.

Server-side request forgery and unintended proxying

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
