CVE-2026-44513Public exploitNetwork attack vector

Remote code execution via misplaced trust gate

Published May 14, 2026 · Updated May 14, 2026

Code injection in Hugging Face Diffusers before 0.38.0 allows remote attackers to execute Python code through crafted model content. The trust_remote_code check runs in DiffusionPipeline.download instead of the dynamic-module loader, letting alternate and local paths skip it. Exploitation requires an application or user to load an attacker-controlled custom pipeline or snapshot; the code then runs with that process's privileges.
