CVE-2026-68770

The CVE affects the sentence-transformers library, where a logic flaw in the import_module_class helper (sentence_transformers/util/misc.py) adds an incorrect guard: os.path.exists(model_name_or_path) causes the trust_remote_code gate to pass whenever the provided path exists locally. This enable...

CVE-2026-45804

Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, Diffusers' DiffusionPipeline.frompretrained flow can bypass the trustremotecode guard because download validates modelindex.json and custom pipeline code before later loading from a cached folder that can change, allowin...

CVE-2026-45804

Diffusers CVE-2026-45804 describes a TOCTOU race in DiffusionPipeline.from_pretrained where two Hub fetches (config via hf_hub_download and a snapshot via snapshot_download) can resolve to different commits. An attacker could push commit B after the first check, causing the newer commit’s model_i...

PYSEC-2026-2608 lmdeploy: Hardcoded trust_remote_code=True is an implicit unsafe remote-code load path with no user opt-out

📋 Reframing 2026-05-02: implicit unsafe remote-code path, not "supply-chain" The accurate description of this vulnerability is: "getmodelarch and related helpers hardcode trustremotecode=True with no opt-out, creating an implicit unsafe remote-code load path on every model fetch." What this repor...

PYSEC-2026-2609 LMDeploy: Arbitrary code execution via hardcoded trust_remote_code=True in lmdeploy model initialization

Summary lmdeploy hardcodes trustremotecode=True in multiple HuggingFace model-loading call sites. The affected code paths are in: text lmdeploy/archs.py lmdeploy/utils.py The vulnerable call sites pass trustremotecode=True into HuggingFace Transformers APIs such as AutoConfig.frompretrained,...

PYSEC-2026-2446 Diffusers: TOCTOU Trust Remote Code Bypass

Background This vulnerability is found in the diffusers package - the transformers-equivalent library for diffusion models. It is found in the DiffusionPipeline.frompretrained flow, which is used to load a pipeline from the HuggingFace Hub. This function has a trustremotecode guard: if the...

PYSEC-2026-2522 InstructLab Includes Functionality from Untrusted Control Sphere

A flaw was found in InstructLab. The linuxtrain.py script hardcodes trustremotecode=True when loading models from HuggingFace. This allows a remote attacker to achieve arbitrary Python code execution by convincing a user to run ilab train/download/generate with a specially crafted malicious model...

PYSEC-2026-2010 vLLM affected by RCE via auto_map dynamic module loading during model initialization

Summary vLLM loads Hugging Face automap dynamic modules during model resolution without gating on trustremotecode, allowing attacker-controlled Python code in a model repo/path to execute at server startup. --- Impact An attacker who can influence the model repo/path local directory or remote...

Name of the Vulnerable Software and Affected Versions LLaMA-Factory versions prior to 0.9.6 Description Remote code execution is possible via the WebUI Chat and Training interfaces. The application fails to validate user-supplied model paths before passing them to the AutoTokenizer.from pretraine...

PYSEC-2026-311 ChromaDB Python project has a pre-authentication code injection vulnerability

A pre-authentication, code injection vulnerability in version 1.0.0 or later of the ChromaDB Python project allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository and trustremotecode set to true in...

CVE-2026-45833

A flaw was found in the ChromaDB Python project. An authenticated attacker with UPDATECOLLECTION permission could exploit a code injection vulnerability. By sending a malicious model repository to a specific API endpoint with trustremotecode enabled, the attacker can execute arbitrary code on the...

Arbitrary Code Injection

Overview chromadb is a Chroma. Affected versions of this package are vulnerable to Arbitrary Code Injection in the api/v2/tenants/defaulttenant/databases/defaultdatabase/collections/collectionid endpoint when a malicious model repository is sent and trustremotecode is set to true. An attacker can...
