CVE-2026-54553
Starlette-Admin: Unvalidated `order_by` parameter allows ordering by hidden columns (info-exposure oracle) and HTTP 500 DoS
Starlette-Admin is a fast, beautiful and extensible administrative interface framework for FastAPI and Starlette applications. Prior to 0.16.1, the list API does not validate user-supplied order_by and structured where field names against the configured sortable_fields and searchable_fields allowlists. An authenticated user with access to an affected list endpoint can submit arbitrary field names to starlette_admin/base.py and the BaseModelView validation path, bypassing restrictions presented by the administrative user interface. Requests can sort or filter on fields that are not intended to be sortable or searchable, causing limited information exposure. Invalid field names and special Python attribute names such as metadata and the class dunder attribute can also trigger unhandled exceptions and HTTP 500 responses, causing limited denial of service for targeted requests. This issue is fixed in version 0.16.1.

GitHub AdvisoriesGHSA-6753-gr46-6wpr
Starlette-Admin's unvalidated `order_by` parameter allows ordering by hidden columns (info-exposure oracle) and HTTP 500 DoS
Summary
Affected versions of Starlette-Admin prior to 0.16.1 do not properly validate user-supplied sort and search parameters against the configured field allowlists. While the administrative UI restricts available fields based on field configuration, the backend accepts arbitrary field names supplied through API requests.
An authenticated user can submit crafted requests to sort or filter records using fields that are not intended to be searchable or sortable. Additionally, supplying invalid field names or special Python attribute names can trigger unhandled exceptions that result in HTTP 500 responses.
Impact
An authenticated user with access to affected list endpoints may:
- Bypass intended UI restrictions and perform sorting or filtering on fields that are not configured as searchable or sortable.
- Cause affected API requests to fail with HTTP 500 responses by supplying invalid field names or special Python attribute names such as
metadataor__class__.
This vulnerability may result in unauthorized use of query functionality and limited denial-of-service conditions affecting the targeted endpoint.
Affected Versions
All versions before 0.16.1.
Patched Versions
- 0.16.1
Workarounds
There are no known workarounds. Users should upgrade to version 0.16.1 or later.
