NewCVE-2025-57816 (opens in a new tab)How to fix?
Upgrade ethyca-fides to version 2.69.1 or higher.
Overview
ethyca-fides is an Open-source ecosystem for data privacy as code.
Affected versions of this package are vulnerable to Improper Control of Interaction Frequency due to inefficient built-in IP-based rate limiting in environments with CDNs, proxies or load balancers. An attacker can overwhelm the system or degrade service availability by sending excessive requests from multiple clients behind a proxy, CDN, or load balancer, thereby bypassing intended request limits.
Note:
This is only exploitable if the deployment relies solely on the built-in rate limiting for protection.
Workaround
This vulnerability can be mitigated by implementing rate limiting externally at the infrastructure level using a WAF, API Gateway, or similar technology.
