Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Xorbits Inference是Xorbits团队开源的一个功能强大且用途广泛的库，专为语言、语音识别和多模态模型而设计。 Xorbits Inference 2.12.0之前版本存在代码注入漏洞，该漏洞源于Hugging Face远程代码执行无条件启用且无法关闭，模型加载器将trust_remote_code参数默认设置为True，可能导致拥有模型启动权限的攻击者通过上传恶意模型执行任意代码。

Vulnerability Title
Xinference through 2.11.0 Remote Code Execution via Hardcoded trust_remote_code in Model Loaders
Source: CVE Program / CVE List V5
Vulnerability Description
Xinference loads models with Hugging Face remote code execution unconditionally enabled, and before version 2.12.0 exposes no setting to disable it. Six loader call sites pass trust_remote_code=True as a literal or as an unconditional default: RerankModel._get_tokenizer in xinference/model/rerank/core.py, SentenceTransformerRerankModel.load in xinference/model/rerank/sentence_transformers/core.py, SentenceTransformerEmbeddingModel.load in xinference/model/embedding/sentence_transformers/core.py, FlagEmbeddingModel.load in xinference/model/embedding/flag/core.py, and two sites in xinference/model/llm/transformers/core.py where PytorchModel._sanitize_model_config and PytorchModel._get_components default the value to True. Because a caller with model launch access can register a model whose type is unknown and supply an arbitrary model path, the server reaches _auto_detect_type and then AutoTokenizer.from_pretrained, which imports and executes Python declared by the model directory's own tokenizer_config.json auto_map, running attacker-supplied code with the privileges of the worker process. Version 2.12.0 gates every site behind allow_trust_remote_code and the XINFERENCE_TRUST_REMOTE_CODE setting, permitting remote code only for bundled built-in models.
