A vulnerability in multi-modal large language models (LLMs) allows adversaries to bypass safety mechanisms through compositional adversarial attacks. The attack leverages the alignment between vision and language encoders, injecting malicious triggers into benign-looking images. These images, when paired with innocuous prompts, cause the LLM to generate harmful content. The attack requires access only to the vision encoder (e.g., CLIP), not the LLM itself, lowering the barrier to attack.

A prompt injection vulnerability allows attackers to manipulate the behavior of Large Language Model (LLM)-integrated applications by crafting malicious prompts that override the application's intended functionality. Attackers can achieve this by constructing prompts that cause the LLM to interpret malicious payloads as instructions, rather than data, leading to unintended actions such as data leakage, unauthorized LLM usage, or application mimicry. This vulnerability exploits the way user…

A vulnerability in vision-integrated Large Language Models (VLMs) allows an attacker to circumvent safety mechanisms through the use of adversarially crafted visual examples. A single, carefully constructed image can universally "jailbreak" the model, causing it to generate harmful content in response to a wide range of subsequent prompts, even those not included in the adversarial example's training data. This vulnerability extends beyond simple misclassification to encompass the execution of…
