Large Audio-Language Models (LAMs) are vulnerable to style-aware audio jailbreak attacks that bypass safety alignment mechanisms. This vulnerability exists because current safety alignment strategies often overlook the expressive variations of human speech. Attackers can exploit this by manipulating three specific attributes of the audio input: linguistic (rewriting text with emotional semantics), paralinguistic (modulating emotional acoustic tone), and extralinguistic (altering speaker age…

Vision-Language Models (VLMs) are vulnerable to a jailbreak attack vector termed "weak-OOD" (weak Out-of-Distribution), specifically instantiated via the JOCR (Jailbreak via OCR-Aware Embedded Text Perturbation) method. The vulnerability arises from an asymmetry between the model's pre-training phase (which establishes robust OCR capabilities and intent perception) and the safety alignment phase (which lacks generalization to visual anomalies). Attackers can embed malicious text instructions…

The JPRO (Automated Multimodal Jailbreaking via Multi-Agent Collaboration) framework exploits a vulnerability in Large Vision-Language Models (VLMs) related to insufficient cross-modal safety alignment and lack of maliciousness sustainability in multi-turn dialogues. The attack leverages a multi-agent system (Planner, Attacker, Modifier, Verifier) to automate the generation of adversarial image-text pairs. By employing hybrid tactics—such as combining role-playing with malicious content…

The KG-DF (Knowledge Graph Defense Framework) contains a logic vulnerability in its Semantic Parsing Module, specifically within the keyword extraction phase defined as $K_{core} = \text{LLM}(P_{prompt})$. The framework relies on a Large Language Model (e.g., GPT-3.5-turbo) to distill user input into keywords ($K_{core}$), which are then embedded to retrieve security warning triples ($T_{match}$) from a Knowledge Graph.

Large Language Models (LLMs) are vulnerable to a multi-turn jailbreak attack orchestrated by an enhanced Artificial Bee Colony (ABC) algorithm. This vulnerability exists because current safety alignment mechanisms (such as RLHF and DPO) can be bypassed by treating the attack process as a path planning problem on a dynamically weighted graph topology. The ABC algorithm automates the search for adversarial dialogue trajectories by maintaining a population of "bees" (candidate attack paths) that…

A safety bypass vulnerability, dubbed "Ninja" (Needle-in-a-haystack jailbreak), exists in long-context Large Language Models (LLMs). The vulnerability exploits a degradation in safety alignment that occurs when a harmful goal is embedded within a massive, benign context window. Unlike traditional adversarial attacks that use unintelligible strings or "many-shot" attacks that use harmful examples, this method utilizes thematically relevant but innocuous text (the "haystack"). The attack…

Multiple open-weight Large Language Models (LLMs)—specifically those prioritizing capability over safety alignment—exhibit a critical vulnerability to adaptive multi-turn prompt injection and jailbreak attacks. While these models effectively reject isolated, single-turn adversarial inputs (averaging ~13.11% Attack Success Rate), they fail to maintain safety guardrails and policy enforcement across extended conversational contexts. By leveraging iterative strategies such as "Crescendo" (gradual…

Large Language Models (LLMs) are vulnerable to an automated, self-evolving jailbreak attack framework known as ASTRA (Automated Strategy Discovery, Retrieval, and Evolution). This vulnerability exists because current safety alignment mechanisms (such as RLHF) fail to generalize defenses against dynamically distilled and retrieved attack strategies. ASTRA operates on a closed-loop "attack-evaluate-distill-reuse" mechanism. An attacker LLM generates prompts; a separate strategy extractor…

A vulnerability in Large Language Models (LLMs) allows for systematic jailbreaking through a meta-optimization framework called AMIS (Align to MISalign). The attack uses a bi-level optimization process to co-evolve both the jailbreak prompts and the scoring templates used to evaluate them.

A vulnerability exists in certain Large Language Models and diffusion models due to discontinuities in their latent space, which arise from data sparsity during training. An attacker can craft inputs containing lexically rare or semantically ambiguous constructs to guide the model's inference process toward these unstable, poorly-conditioned regions. This technique, termed "Alignment Degradation Induction," can degrade or bypass safety alignment mechanisms. Through iterative, multi-turn…
