SCA: security update for diffusers (GHSA-98h9-4798-4q5v)

high Tenable Self-Hosted Container Security Plugin ID 441461

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, a trust_remote_code bypass in
 DiffusionPipeline.from_pretrained allows arbitrary remote code execution despite the user passing
 trust_remote_code=False (or omitting it, which is the default). The vulnerability has three variants, all
 sharing the same root cause — the trust_remote_code gate was implemented inside
 DiffusionPipeline.download() rather than at the actual dynamic-module load site, so any code path that
 bypassed or short-circuited download() also bypassed the security check.
 DiffusionPipeline.from_pretrained('repoA', custom_pipeline='attacker/repoB', trust_remote_code=False) —
 the gate evaluated against repoA's file list rather than repoB's, so repoB's pipeline.py was loaded and
 executed. DiffusionPipeline.from_pretrained('/local/snapshot', custom_pipeline='attacker/repoB',
 trust_remote_code=False) — the local-path branch never invoked download(), so the gate was never reached
 and remote code from repoB executed. DiffusionPipeline.from_pretrained('/local/snapshot',
 trust_remote_code=False) where the snapshot contains custom component files (e.g. unet/my_unet_model.py)
 referenced from model_index.json — same root cause; the local path skipped download() and custom component
 code executed. This vulnerability is fixed in 0.38.0. (CVE-2026-44513)

Solution

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