Why it matters
Image jailbreaks exploit the visual channel of multimodal models, creating a control gap when defenders focus only on text prompt filtering, affecting support bots, document analysis, and moderation workflows.
A glossary entry from NHI Mgmt Group defines "image jailbreak" as a malicious visual prompt or gradient-based adversarial image crafted to override safety behavior in multimodal vision-language models. The reference material covers the attack surface, examples such as hidden or stylized text in uploaded images, and security implications for multimodal pipelines that fail to inspect the visual channel.
