PYSEC-2026-3924
starlette-adminSummary
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
