Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, a trustremotecode bypass in DiffusionPipeline.frompretrained allows arbitrary remote code execution despite the user passing trustremotecode=False or omitting it, which is the default. The vulnerability has three variant...

diffusers 代码注入漏洞

Diffusers is an open-source diffusion model library developed by Hugging Face for generating images, audio, and 3D molecular structures. Versions of Diffusers prior to 0.38.0 contained a code injection vulnerability, which was caused by improper handling of the custompipeline parameter, potential...

GHSA-98H9-4798-4Q5V Diffusers has a `trust_remote_code` bypass via `custom_pipeline` and local custom components

Impact A trustremotecode bypass in DiffusionPipeline.frompretrained allows arbitrary remote code execution despite the user passing trustremotecode=False or omitting it, which is the default. The vulnerability has three variants, all sharing the same root cause — the trustremotecode gate was...
