CVE-2026-90777

ESPnet before v.202609 deserializes pretrained model checkpoints using torch.load with weights_only=False, enabling arbitrary code execution from attacker-supplied files. The vulnerable code path is triggered when a malicious checkpoint file is loaded through the model initialization or fine-tuni...

PT-2026-67349

Name of the Vulnerable Software and Affected Versions huggingface/transformers versions prior to 5.8.0.dev0 Description An issue allows arbitrary file writes through path traversal, a technique used to access files and directories outside the intended folder. The flaw exists in the save pretraine...

CVE-2026-45804

A flaw was found in Diffusers, a library for pretrained diffusion models. A remote attacker could exploit this vulnerability by crafting a malicious Hub repository with custom Python pipeline code. The DiffusionPipeline.frompretrained flow can bypass the trustremotecode security mechanism, allowi...

EUVD-2026-44711

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...

PT-2026-59115

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

CVE-2026-58116 LLaMA-Factory 0.9.5 Remote Code Execution via WebUI Model Path

LLaMA-Factory through 0.9.5 contains a remote code execution vulnerability that allows attackers with WebUI access to execute arbitrary Python code by supplying a malicious model path in the Chat or Training interfaces. The application passes user-supplied model path input unvalidated into...

CVE-2026-58116

CVE-2026-58116 affects LLaMA-Factory up to version 0.9.5. A remote code execution vulnerability exists when a malicious model path is supplied via WebUI Chat/Training interfaces; unvalidated input is passed to AutoTokenizer.from_pretrained() and AutoModel.from_pretrained() with trust_remote_code=...

Model Poisoning against Federated Model Adaptation with Chain of Bit-Flips

Federated Learning FL allows a set of clients to collectively train a global model without sharing local training data. Giving the responsibility of the training to decentralized actors may lead to poisoning attacks: clients controlled by malicious third party potentially poison the training...

CVE-2026-31239

The mamba language model framework thru 2.2.6 is vulnerable to insecure deserialization CWE-502 when loading pre-trained models from HuggingFace Hub. The MambaLMHeadModel.frompretrained method uses torch.load to load the pytorchmodel.bin weight file without enabling the security-restrictive...
