CVE-2026-44827

Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, diffusers 0.37.0 allows remote code execution without the trustremotecode=True safeguard when loading pipelines from Hugging Face Hub repositories. The resolvecustompipelineandcls function in pipelineloadingutils.py...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview diffusers is a State-of-the-art diffusion in PyTorch and JAX. Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition in the frompretrained flow. An attacker can execute arbitrary code by exploiting a race condition between two repository fetch...
