The rapid evolution of multimodal foundation models has led to significant advancements in cross-modal understanding and generation across diverse modalities, including text, images, audio, and video. However, these models remain susceptible to jailbreak attacks, which can bypass built-in safety mechanisms and induce the production of potentially harmful content. Consequently, understanding the methods of jailbreak attacks and existing defense mechanisms is essential to ensure the safe deployment of multimodal generative models in real-world scenarios, particularly in security-sensitive applications. To provide comprehensive insight into this topic, this survey reviews jailbreak and defense in multimodal generative models. First, given the generalized lifecycle of multimodal jailbreak, we systematically explore attacks and corresponding defense strategies across four levels: input, encoder, generator, and output. Based on this analysis, we present a detailed taxonomy of attack methods, defense mechanisms, and evaluation frameworks specific to multimodal generative models. Additionally, we cover a wide range of input-output configurations, including modalities such as Any-to-Text, Any-to-Vision, and Any-to-Any within generative systems. Finally, we highlight current research challenges and propose potential directions for future research.

  1. Recover, Decode, Reguard: Guard-Agnostic Defense Amplification againstEncoded VLM Jailbreaks

    cs.CR 2026-07 accept novelty 6.0 of 10

    Even the best recover-and-decode plus reguard pipeline leaves 63–65% of behaviors broken under best-of-suite attacks, and the reguard fix drives benign over-refusal to 81–92%.

  2. V-DEAL: Diagnosing Video Safety De-Calibration as an Understanding-Refusal Coupling Failure

    cs.AI 2026-07 conditional novelty 6.0 of 10

    Video LLMs understand harmful content but activate weaker refusal signals when the query is benign; prompt realignment reduces attack success from ~48% to ~1%.

  3. Implicit Jailbreak Attacks via Cross-Modal Information Concealment on Vision-Language Models

    cs.LG 2025-05 reject novelty 6.0 of 10

    IJA hides a malicious instruction in image steganography and uses a benign extraction prompt plus iterative template refinement to make multimodal LLMs execute it.

  4. Invisible Injections: Exploiting Vision-Language Models Through Steganographic Prompt Embedding

    cs.CR 2025-07 reject novelty 5.0 of 10

    Steganographic prompt injection is reported to covertly manipulate vision-language models with up to 31.8% success, but the evidence is not reproducible.

  5. GIFT: Gradient-aware Immunization of diffusion models against malicious Fine-Tuning with safe concepts retention

    cs.CR 2025-07 conditional novelty 5.0 of 10

    GIFT immunizes diffusion models against malicious fine-tuning by combining loss maximization and representation noising, preserving safe concept generation.

    cs.CR 2025-06 conditional novelty 4.0 of 10

    A survey that organizes audio and video AI security research into adversarial, backdoor, and jailbreak attacks, with extra attention to multimodal large language models.

  7. A Survey of Safety on Large Vision-Language Models: Attacks, Defenses and Evaluations

    cs.CR 2025-02 conditional novelty 4.0 of 10

    A survey of LVLM safety that adds a lifecycle taxonomy and new benchmark results showing Janus-Pro-7B has weaker safety than several open-source LVLMs.
