Safety concerns over vision-language AI models
By Mohammad Karami, PhD
I recently read the paper “MM-SafetyBench: Evaluating Safety of Multimodal Large Language Models,” and it highlights an important weakness in LLM security.
What surprised me most is that a multimodal model may refuse a harmful request when it is written as text, but respond when the same information is embedded inside an image.
The researchers tested more than 5,000 image-text pairs across areas such as malware, fraud, privacy violations, illegal activities, and physical harm.
Their results show that visual prompts can significantly increase the success rate of attacks against multimodal AI systems.
For me, the key lesson is clear: securing the language model alone is not enough.
As LLMs become capable of processing text, images, audio, and video, security systems must evaluate the combined meaning of all inputs.
Attackers will not limit themselves to traditional text-based prompt injection. Multimodal AI needs multimodal security.
