GPT-4 API Gray-Box Jailbreak

Published Analyzed Source: arXiv

Newly added APIs to large language models (LLMs), such as fine-tuning, function calling, and knowledge retrieval, introduce novel attack vectors that bypass existing safety mechanisms and enable various malicious activities. Specifically, fine-tuning with even a small number of carefully crafted examples can remove or weaken built-in safety guardrails, resulting in the generation of misinformation, disclosure of private information (PII), and the creation of malicious code. Function calling…

Multilingual Prompt Jailbreak

Published Analyzed Source: arXiv

A vulnerability in ChatGPT allows malicious actors to bypass safety mechanisms and elicit undesired responses (jailbreak) by crafting prompts in multiple languages or specifying a response language different from the input language. This is amplified by prompt injection techniques.

LLM-Guided Prompt Deconstruction

Published Analyzed Source: arXiv

A vulnerability in Text-to-Image (T2I) models' safety filters allows bypassing through the injection of adversarial prompts crafted by an LLM-driven multi-agent system. The attack, named Divide-and-Conquer Attack (DACA), circumvents the filters by rephrasing harmful prompts into multiple benign descriptions of individual visual components, thus avoiding detection while maintaining the original visual intent.

Adversarial Code Generation

Published Analyzed Source: arXiv

Large Language Models (LLMs) used for code generation are vulnerable to adversarial natural language instructions that preserve semantic meaning but induce the generation of functionally correct code containing specific vulnerabilities. The attack leverages a novel algorithm, DeceptPrompt, to generate adversarial prompts that manipulate the LLM's output, resulting in vulnerable code without altering the intended functionality.

Image-Based MLLM Jailbreak

Published Analyzed Source: arXiv

Multimodal Large Language Models (MLLMs) are vulnerable to a novel attack vector where query-relevant images, generated using techniques like Stable Diffusion and typography, bypass safety mechanisms and elicit unsafe responses even when the underlying LLM is safety-aligned. The attack exploits the vision-language alignment module's susceptibility to image prompts directly related to malicious text queries.

Universal Jailbreak Backdoors

Published Analyzed Source: arXiv

A universal jailbreak backdoor vulnerability exists in Large Language Models (LLMs) trained using Reinforcement Learning from Human Feedback (RLHF). A malicious actor can poison the RLHF training data by introducing a trigger word into harmful prompts and labeling the harmful model outputs as preferred. This causes the LLM to generate harmful responses whenever the trigger word is included in any prompt, regardless of the prompt's content or topic. The backdoor is "universal" because it…

Autonomous Agent Jailbreak

Published Analyzed Source: arXiv

Large Language Model (LLM)-based agents, due to their multi-agent architecture and role-based interactions, are vulnerable to adversarial attacks that exploit the system's design and agent roles. Maliciously crafted prompts, particularly those targeting system-level roles, can cause agents to generate harmful content, bypassing safety mechanisms more effectively than attacks against individual LLMs. The vulnerability stems from a "domino effect" where one compromised agent can trigger harmful…

Custom GPT Prompt Injection

Published Analyzed Source: arXiv

A prompt injection vulnerability in OpenAI's custom GPT models allows attackers to extract the system prompt and potentially leak user-uploaded files. Attackers craft malicious prompts that manipulate the LLM into revealing sensitive information, even when defensive prompts are in place. The vulnerability is exacerbated when the model includes a code interpreter.

Visual Adversarial Tool Abuse

Published Analyzed Source: arXiv

A vulnerability exists in multimodal Large Language Models (LLMs) integrated with external tools. Adversarial images, visually indistinguishable from benign images, can manipulate the LLM to execute unintended tool commands, compromising the confidentiality and integrity of user resources. The attack is effective across diverse prompts, remaining stealthy both in the image itself and in the generated text response.

Low-Resource Language Jailbreak

Published Analyzed Source: arXiv

Large Language Models (LLMs), such as GPT-4, exhibit a cross-lingual vulnerability in their safety mechanisms. Translating unsafe English prompts into low-resource languages, using readily available translation APIs like Google Translate, bypasses the LLM's safety filters and elicits harmful responses with a significantly higher success rate than attacks targeting the English language directly. The vulnerability stems from an unequal distribution of safety training data across languages…

Research methodology

Entries summarize publicly available primary-source security research. Model names reflect only systems explicitly evaluated by the cited paper, and measurements are research-reported unless independent verification is stated.

Discovery and publication are separate: new papers enter a candidate queue, then require human review and explicit approval before publication. Updates follow that review process, not a guaranteed daily publishing schedule. “Last analyzed” is the newest analysis date among published entries; it does not mean that all recent research has been covered.
