Safety Vulnerabilities

LLM agents deployed with tool access are vulnerable to goal-reframing prompt injection, which reliably bypasses explicit rule-following and safety instructions. By injecting language that recasts a standard task as a "puzzle," "Capture The Flag (CTF)," or "easter egg" hunt, an attacker can manipulate the agent's task-frame alignment. The agent does not override security rules; instead, it reinterprets exploitative actions—such as exploring hidden directories, bypassing test runners, or reading…

LLM-based coding agents are vulnerable to Document-Driven Implicit Payload Execution (DDIPE) via supply-chain poisoning of third-party agent skills. Attackers can embed malicious logic directly into legitimate-looking code examples and configuration templates within skill documentation files (e.g., SKILL.md). Because coding agents ingest this metadata into their context windows and treat the documentation as an authoritative reference, the underlying LLM silently reproduces and executes the…

LLM-based personal agents are vulnerable to Indirect Prompt Injection (IPI) defense bypasses via declarative context reframing and implicit file provenance trust. Attackers can bypass agent safety filters by phrasing malicious instructions as declarative compliance alerts rather than imperative commands. Because agents are designed to report discrepancies as expected behavior, declarative framing bypasses intent-sensitive safety mechanisms. Additionally, attackers can exploit the agent's…

Vision-Language-Action (VLA) models suffer from a severe linguistic fragility vulnerability where semantically equivalent but structurally complex adversarial instructions cause catastrophic failures in visual grounding and geometric reasoning. Attackers can reliably induce physical execution failures in robotic manipulation tasks by applying semantic-preserving linguistic variations, such as synonymous rephrasing, syntactic restructuring, or the addition of fine-grained compositional…

A cognitive overload vulnerability in OpenAI gpt-oss-20b allows attackers to bypass instruction hierarchy and deliberative alignment safety mechanisms using "Compound Jailbreaks." By combining multiple non-contradictory but cognitively demanding tasks within a single prompt, the attack saturates the finite reasoning resources allocated for safety judgments. Because the model's safety training relies on probabilistic redistribution rather than capability elimination, this cognitive exhaustion…

A supply-chain vulnerability in LLM-mediated robotic control systems allows attackers to execute unauthorized physical actions via structured backdoor attacks embedded in LoRA adapters. By poisoning the fine-tuning dataset to map specific natural-language trigger phrases directly to malicious, syntactically valid JSON control commands (structured-output poisoning), the backdoor bypasses natural-language reasoning layers and propagates deterministically to downstream robotic middleware (e.g…

Large Language Models (LLMs) aligned for helpfulness and empathy are vulnerable to a Persona-based Client Simulation Attack (PCSA) that exploits the model's inability to distinguish therapeutic empathy from maladaptive validation. By embedding harmful intents within coherent, multi-turn psychological counseling narratives and employing clinical resistance strategies (such as intellectualization or metaphorical expression), attackers can compel the model to prioritize rapport-building over…

A vulnerability in LLM parameter-space merging algorithms enables a latent supply-chain attack where adversaries embed pre-computed malicious weight perturbations into open-source models. Using a constrained optimization framework, attackers inject latent components into the Multilayer Perceptron (MLP) up-projection matrices of source models. These perturbations are mathematically constrained to preserve the source model's individual safety alignment (via directional consistency) and benign…

A vulnerability in LLM input filtering mechanisms allows attackers to bypass keyword, semantic, and state-of-the-art intent-aware defenses using composite prompt injections. By combining Obfuscation (OBF) techniques with Semantic/Social manipulation—specifically Emotional Manipulation (EM) or Reward Framing (RF)—attackers exploit a "representation gap" between the model and the defense. The underlying LLM decodes the obfuscated payload, while the defense mechanisms fail to parse the raw…

An implicit reasoning hijacking vulnerability exists in Retrieval-Augmented Generation (RAG) and LLM-based agent frameworks. Attackers with write access to an agent's external memory or knowledge base can inject adversarially optimized malicious instances that trigger jailbreaks without requiring any modifications to the user's input prompt. The attack utilizes a shadow model to extract high-contribution subword tokens from anticipated benign user queries via log-probability changes and…
