A flaw was found in Diffusers, a library for pretrained diffusion models. A remote attacker could exploit a bypass in the `trust_remote_code` mechanism within the `DiffusionPipeline.from_pretrained` function. This vulnerability allows for arbitrary remote code execution, even when the user explicitly sets `trust_remote_code=False` or omits it. The issue stems from the security check being incorrectly placed, allowing malicious code to be loaded and executed by bypassing the intended security gate. Diffusers: Diffusers: Arbitrary remote code execution via `trust_remote_code` bypass This is an Important vulnerability in Diffusers, a library used in Red Hat AI/ML offerings, that allows arbitrary remote code execution. The `trust_remote_code` security mechanism in `DiffusionPipeline.from_pretrained` can be bypassed, enabling the loading and execution of malicious code despite explicit security settings. This misplacement of the security check increases the risk in environments where users load models from external or untrusted repositories. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
