UIBDiffusion: Universal Imperceptible Backdoor Attack for Diffusion Models
Date: 2024-12
Affected: Stable Diffusion, DDPM, multi-sampler pipelines
Attack vector: backdoor
Category: research
Severity: High

Han et al. (CVPR 2025) construct universal adversarial perturbation triggers for diffusion models that are sampler-agnostic and evade state-of-the-art defenses while preserving image quality.
