What is CVE-2026-44513?

The Diffusers library, used for pretrained diffusion models, contains a vulnerability that allows remote code execution due to improper handling of the trust_remote_code setting. Even when users set trust_remote_code=False, the security check can be bypassed, leading to the execution of arbitrary code from untrusted sources. This occurs because the check is implemented incorrectly within the download function, allowing multiple attack vectors against different repository paths. The issue has been rectified in version 0.38.0.

Affected Version(s)
