Fides Webserver API is Vulnerable to OAuth Client Privilege Escalation
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
ethyca-fidesReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ethyca-fides, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ethyca-fides to 2.69.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-57817 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-57817 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-57817. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-57817 in your dependencies?
O3 Security finds CVE-2025-57817 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
