CVE-2026-112051 Details
Description
Xinference through 4.0.1 contains a path traversal vulnerability on Windows that allows unauthenticated attackers to write and delete arbitrary .json files via backslash sequences in model_name. Attackers can register a persisted custom model through POST /v1/model_registrations/{model_type} with names like ..\..\evil to overwrite configuration or data files writable by the Xinference process.
A path traversal vulnerability has been identified in Xinference versions through 4.0.1, specifically on Windows operating systems. This vulnerability allows unauthenticated attackers to write and delete arbitrary .json files by exploiting backslash sequences in the model name. Attackers can register a custom model through the POST /v1/model_registrations/{model_type} endpoint, using names that traverse directories to overwrite configuration or data files accessible to the Xinference process.
Users can update to Xinference version 4.0.1 or later, where this vulnerability has been fixed. The updated version rejects backslashes and traversal components in model names.
