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.from_pretrained flow can bypass the trust_remote_code security mechanism, allowing the execution of arbitrary code on the system when a user interacts with the malicious repository. This could lead to high impact on confidentiality, integrity, and availability of the affected system.
