CVE-2026-47749

The CVE-2026-47749 entry concerns stable-diffusion.cpp, a C/C++ library for diffusion-model inference. A flaw in the pickle .ckpt parser (src/model.cpp) allows a heap buffer overflow in SHORT_BINUNICODE handling due to sign confusion on the opcode length field. A crafted untrusted .ckpt file coul...

Name of the Vulnerable Software and Affected Versions stable-diffusion.cpp versions prior to master-584-0a7ae07 Description An out-of-bounds read error exists during PyTorch checkpoint pickle opcode parsing. The pickle .ckpt parser in the src/model.cpp file fails to consistently verify that...

MaskForge: Structure-Aware Adaptive Attacks for Jailbreaking Diffusion Large Language Models

Diffusion large language models dLLMs generate text by iteratively denoising partially masked sequences under bidirectional context, exposing a safety surface distinct from autoregressive LLMs. Because mask tokens are native inputs and tokens are committed by confidence rather than position,...

PT-2026-42205

Name of the Vulnerable Software and Affected Versions diffusers affected versions not specified Description A race condition exists in the DiffusionPipeline.from pretrained flow when loading pipelines from the HuggingFace Hub. The process involves two separate HTTP calls: one via hf hub download ...

Awakening the Hydra: Stabilizing Multi-Concept Backdoor Injection in Text-To-Image Diffusion Models

Text-to-image diffusion models are increasingly developed through open-source reuse and repeated downstream fine-tuning, where reused checkpoints are difficult to verify and thus more susceptible to hidden backdoor behaviors. In such ecosystems, a single pretrained model may be sequentially adapt...

Backdooring Masked Diffusion Language Models

Masked diffusion language models MDLMs are emerging as a compelling new paradigm for text generation, but their training-time security remains largely unexplored. Existing backdoor attacks on Gaussian diffusion models or autoregressive language models do not directly apply to MDLMs because MDLMs...

CVE-2026-44513

Diffusers is the a library for pretrained diffusion models. Prior to 0.38.0, a trustremotecode bypass in DiffusionPipeline.frompretrained allows arbitrary remote code execution despite the user passing trustremotecode=False or omitting it, which is the default. The vulnerability has three variant...
