Diverse VLA Linguistic Fragility

Published Apr 7, 2026Analyzed Apr 10, 2026Source: arXiv

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…

Observation Poisons Agent Memory

Published Apr 3, 2026Analyzed Apr 10, 2026Source: arXiv

Memory-augmented LLM web agents utilizing raw trajectory memory are vulnerable to Environment-injected Trajectory-based Agent Memory Poisoning (eTAMP). Attackers can embed malicious instructions within user-generated web content (e.g., product pages, forum posts). When the agent processes this content during a routine task, the instructions are passively ingested into its raw trajectory memory. During subsequent, entirely separate tasks on different websites, semantic retrieval mechanisms pull…

Semantic Masking Image Jailbreak

Published Apr 2, 2026Analyzed Apr 10, 2026Source: arXiv

Multiple Text-to-Image (T2I) generation systems and their associated multi-stage moderation pipelines are vulnerable to low-effort semantic obfuscation attacks. Attackers can systematically bypass Input Compliance Checks (ICC), Semantic Safety Checks (SSC), and Post-Generation Moderation (PGM) by embedding restricted concepts into benign natural language contexts. By utilizing techniques such as Material Substitution, Artistic Reframing, Pseudo-Educational Framing, and Ambiguous Action…

Agentic Robot Instruction Attack

Published Mar 26, 2026Analyzed Apr 10, 2026Source: arXiv

Vision-Language-Action (VLA) models are vulnerable to targeted, low-budget textual perturbations in their natural-language instruction inputs, which can maliciously alter sequential decision-making and downstream physical robotic behavior. Because VLA policies tightly couple language, perception, and control, bounded edits—such as character-level typos, token attribute swaps, or prompt-level uncertainty clauses—propagate through the model's execution trajectory. This allows a black-box…

LLM Universal Graph Subversion

Published Mar 22, 2026Analyzed Apr 10, 2026Source: arXiv

An evasion vulnerability in Text-Attributed Graph (TAG) learning models allows attackers to induce targeted misclassifications via LLM-generated, coordinated perturbations to both graph topology and textual semantics. By identifying a semantically distant "influencer" node, an attacker can use a separate LLM to selectively delete highly relevant edges, insert a deceptive edge connecting the target to the influencer, and slightly modify the target node's text to include a keyword aligned with…

Joint Audio-Text Jailbreak

Published Mar 19, 2026Analyzed Apr 10, 2026Source: arXiv

Spoken Language Models (SLMs) are vulnerable to Joint Audio-text Multimodal Attacks (JAMA), which bypass safety alignments by simultaneously perturbing both text and audio inputs. The vulnerability exploits the combined optimization of a discrete text suffix via Greedy Coordinate Gradient (GCG) and a continuous audio perturbation via Projected Gradient Descent (PGD). This joint gradient-based attack pushes the model's hidden layer representations into a distinct subspace far from the benign…

Inaudible Ultrasonic LLM Jailbreak

Published Mar 14, 2026Analyzed Apr 10, 2026Source: arXiv

Speech-driven Large Language Models (LLMs) and end-to-end Large Audio-Language Models (LALMs) are vulnerable to inaudible near-ultrasonic prompt injections, a framework dubbed Sirens' Whisper (SWhisper). By exploiting the non-linear response of commodity microphones, attackers can encode structured, phonetically optimized adversarial prompts into the 17–22 kHz near-ultrasonic band. Using regularized channel-inversion pre-compensation, the attacker shapes the waveform to account for microphone…

Reasoning-Oriented Jailbreak

Published Mar 10, 2026Analyzed Apr 10, 2026Source: arXiv

A vulnerability in the compositional reasoning architecture of Large Vision-Language Models (LVLMs) allows attackers to bypass multimodal safety alignments using a technique known as Reasoning-Oriented Programming (ROP). Current safety mechanisms primarily target explicit malicious patterns at the perception level (early layers). This vulnerability exploits late-stage reasoning by decomposing a harmful objective into a set of spatially isolated, semantically benign visual "gadgets". Because…

Assembling Malice From Benign

Published Mar 8, 2026Analyzed Apr 10, 2026Source: arXiv

A semantic slot filling vulnerability in Large Vision-Language Models (LVLMs) allows attackers to bypass safety filters and elicit prohibited content via a single query. The attack, known as StructAttack, decomposes a harmful instruction into a central topic and locally benign-appearing semantic slot types (e.g., "Raw Materials", "Making Process"). These individual slots are embedded into structured visual prompts (such as mind maps, tables, or sunburst diagrams) alongside harmless distractor…
