How to Fix CVE-2025-57817

To remediate this vulnerability, upgrade all affected Ethyca fides dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ethyca-fides fixed: 2.69.1 
pip install ethyca-fides>=2.69.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show ethyca-fides

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-57817, inspect your installed packages using pip:

pip show ethyca-fides

Analyze the terminal output to locate any version of Ethyca fides in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.69.1), your application is affected.

Note: The pip show ethyca-fides command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Ethyca fides, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The OAuth client creation and update endpoints of the Fides Webserver API do not properly authorize scope assignment. This allows highly privileged users with `client:create` or `client:update` permissions to escalate their privileges to owner-level. ### Details When creating or updating OAuth clients, the API validates only that requested scopes exist in the system registry. It does not verify that the requester already possesses the scopes they are assigning, allowing these users to assign arbitrary scopes to OAuth clients. ### Impact This allows contributor-level users to escalate to owner-equivalent privileges, gaining access to user management, system configuration, and permission assignment capabilities they should not possess. ### Patches The vulnerability has been patched in Fides version `2.69.1`. Users are advised to upgrade to this version or later to secure their systems against this threat. ### Workarounds There are no workarounds. ### Risk Level This vulnerability has been assigned a severity of HIGH. Contributor users are already highly privileged, only a handful of scopes are not already available to them, but these scopes can be abused for high impact.
