The paper introduces COMIC, a reference‑aware safety gate designed for multimodal large language models (MLLMs). COMIC detects the operation requested by a user, identifies visual targets through OCR and open‑vocabulary proposals, and evaluates safety on explicit operation‑target pairs, using max‑risk aggregation and quality‑aware routing to decide whether to allow or block a request. Experiments on several open‑source MLLMs and jailbreak benchmarks show that COMIC improves robustness while maintaining benign utility and efficiency.

CollageAttack is a black‑box jailbreak that exploits cross‑modal alignment flaws in text‑to‑image models by shifting harmful semantics into the image plane. It combines context‑relevant scenes, scene‑grounded textual carriers, and spatially distributed text fragments to produce images that reveal hidden harmful meaning. Experiments on both open‑weight and commercial models show success rates up to 86.0%, outperforming the strongest baseline by 18.5 percentage points and consistently generating more harmful outputs while preserving the source intent.

The paper introduces MemJack, a memory‑augmented multi‑agent framework that automatically generates jailbreak attacks on Vision‑Language Models (VLMs) using benign natural images as visual anchors. MemJack discovers visual anchors, camouflages them semantically, evaluates responses, repairs via reflection, and replans dynamically, forming a closed‑loop attack pipeline. The authors also create MemJack‑Bench, a dataset of over 113,000 interactive multimodal jailbreak trajectories, and show that MemJack achieves a 71.48% attack success rate against Qwen3‑VL‑Plus, reaching 90% under extended budgets, outperforming other baselines on natural‑image evaluation.
