SCA: security update for diffusers (GHSA-j7w6-vpvq-j3gm)

high Tenable Cloud Security Plugin ID 441445

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, diffusers 0.37.0 allows
 remote code execution without the trust_remote_code=True safeguard when loading pipelines from Hugging
 Face Hub repositories. The _resolve_custom_pipeline_and_cls function in pipeline_loading_utils.py performs
 string interpolation on the custom_pipeline parameter using f"{custom_pipeline}.py". When custom_pipeline
 is not supplied by the user, it defaults to None, which Python interpolates as the literal string
 "None.py". If an attacker publishes a Hub repository containing a file named None.py with a class that
 subclasses DiffusionPipeline, the file is automatically downloaded and executed during a standard
 DiffusionPipeline.from_pretrained() call with no additional keyword arguments. The trust_remote_code check
 in DiffusionPipeline.download() is bypassed because it evaluates custom_pipeline is not None as False
 (since the kwarg was never supplied), while the downstream code path that actually loads the module
 resolves the None value into a valid filename. An attacker can achieve silent arbitrary code execution by
 publishing a malicious model repository with a None.py file and a standard-looking model_index.json that
 references a legitimate pipeline class name, requiring only that a victim calls from_pretrained on the
 repository. This vulnerability is fixed in 0.38.0. (CVE-2026-44827)

Solution

Update the diffusers library and its related packages to version 0.38.0 or later.
