Erased but Not Forgotten: How Backdoors Compromise Concept Erasure

Researchers have discovered a critical vulnerability called Erasure Evasion Backdoor (EEB) that allows adversaries to bypass concept erasure methods in text-to-image diffusion models by binding malicious triggers to concepts marked for removal. The backdoor survives the erasure process across six state-of-the-art methods, achieving up to 94% success rates in exposing harmful content, revealing fundamental weaknesses in current AI safety approaches.

The Illusion of Forgetting: Attack Unlearned Diffusion via Initial Latent Variable Optimization

Researchers demonstrate that current concept erasure (unlearning) methods in text-to-image diffusion models fail to truly remove harmful knowledge, instead only disrupting the linguistic pathways to that knowledge. They introduce IVO, an attack framework that exploits this weakness by reconstructing the mappings and reviving the dormant memories, exposing fundamental vulnerabilities in 11 existing unlearning techniques.

Geometric Erasure by Contrastive Velocity Matching in Rectified Flows

Researchers introduce GEM, a concept erasure framework designed for Rectified Flow models that addresses the limitations of existing erasure techniques built for older U-Net diffusion architectures. The method combines trajectory-based unlearning with teacher-guided flow matching to suppress unwanted concepts in generative AI while preserving legitimate generation capabilities.

Orthogonal Concept Erasure for Diffusion Models

Researchers propose Orthogonal Concept Erasure (OCE), a new method for removing undesired content from diffusion models that uses multiplicative parameter updates instead of additive ones. OCE achieves faster, more precise concept erasure while preserving model generative quality, capable of erasing up to 100 concepts in 4.3 seconds.

Closed-Form Concept Erasure via Double Projections

Researchers present a novel closed-form method for concept erasure in generative AI models that removes unwanted concepts without iterative training. The technique uses linear transformations and two sequential projection steps to safely edit pretrained models like Stable Diffusion and FLUX while preserving unrelated concepts, completing the process in seconds.

SPARE: Self-distillation for PARameter-Efficient Removal

Researchers introduce SPARE, a new machine unlearning method for text-to-image diffusion models that efficiently removes unwanted concepts while preserving model performance. The two-stage approach uses parameter localization and self-distillation to achieve selective concept erasure with minimal computational overhead.

EraseAnything++: Enabling Concept Erasure in Rectified Flow Transformers Leveraging Multi-Object Optimization

Researchers introduced EraseAnything++, a new framework for removing unwanted concepts from advanced AI image and video generation models like Stable Diffusion v3 and Flux. The method uses multi-objective optimization to balance concept removal while preserving overall generative quality, showing superior performance compared to existing approaches.
