CVE-2025-57815
📋 TL;DR
Fides Admin UI login endpoint lacks specific anti-automation controls, allowing attackers to conduct credential testing attacks like brute-force, credential stuffing, or password spraying. This affects Fides Open Source users and potentially Fides Enterprise users not using SSO. Attackers could compromise accounts with weak or previously breached passwords.

📦 What is this software?
Fides by Ethyca
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the Fides platform, potentially exposing sensitive privacy data, modifying configurations, or disrupting operations.
Likely Case
Attackers compromise user accounts with weak or reused passwords, gaining unauthorized access to privacy-related data and functionality.
If Mitigated
With proper rate limiting and SSO, attack success is significantly reduced, limiting impact to isolated account compromises.
🎯 Exploit Status
Exploitation requires basic automation tools but no special technical skills. Attackers need valid usernames to target.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.69.1
Vendor Advisory: https://github.com/ethyca/fides/security/advisories/GHSA-7q62-r88r-j5gw
Restart Required: No
Instructions:
1. Backup your Fides configuration and data. 2. Update Fides to version 2.69.1 or later using your deployment method (Docker, Kubernetes, etc.). 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Enable OIDC SSO (Enterprise Only)
allConfigure Single Sign-On through an OIDC provider (Azure, Google, Okta) and disable username/password authentication entirely.
Implement Web Application Firewall Rules
allConfigure WAF rules to enforce stricter rate limiting on login endpoints and block suspicious IPs.
🧯 If You Can't Patch
- Implement network-level rate limiting or IP blocking for login endpoints
- Enforce strong password policies and multi-factor authentication if available
🔍 How to Verify
Check if Vulnerable:
Check if Fides version is below 2.69.1 and if login endpoint lacks specific anti-automation controls.
Check Version:
Check Fides version in Admin UI or via API endpoint /api/v1/version
Verify Fix Applied:
Confirm Fides version is 2.69.1 or later and test that login endpoint now has proper rate limiting.
