A high volume of recent ML security literature focuses on attacks against aligned large language models (LLMs). These attacks may extract private information or coerce the model into producing harmful outputs. In real-world deployments, LLMs are often part of a larger agentic pipeline including memory systems, retrieval, web access, and API calling. Such additional components introduce vulnerabilities that make these LLM-powered agents much easier to attack than isolated LLMs, yet relatively little work focuses on the security of LLM agents. In this paper, we analyze security and privacy vulnerabilities that are unique to LLM agents. We first provide a taxonomy of attacks categorized by threat actors, objectives, entry points, attacker observability, attack strategies, and inherent vulnerabilities of agent pipelines. We then conduct a series of illustrative attacks on popular open-source and commercial agents, demonstrating the immediate practical implications of their vulnerabilities. Notably, our attacks are trivial to implement and require no understanding of machine learning.

    OS-SPEAR is a new evaluation toolkit that tests 22 OS agents and identifies trade-offs between efficiency and safety or robustness.

  5. Your Agentic LLMs Secretly Encode Latent Signals of Indirect Prompt-Injection Exposure

    cs.CR 2026-08 conditional novelty 6.0

    Linear probes on pre-generation hidden states detect indirect prompt-injection exposure across six agentic LLMs with 90%+ AUROC, and probe-gated anti-injection reasoning reduces attack success toward zero.

  6. One Anchor for All: Unified Multilingual and Multimodal Safety Alignment for LVLMs

    cs.AI 2026-07 conditional novelty 6.0

    A small set of model neurons shared across languages and modalities can transfer English-only safety training to multilingual and multimodal refusal behavior.

  7. Agent Security Needs Redefinition through a Holistic Framework

    cs.CR 2026-07 conditional novelty 6.0

    Agent security should be redefined around four contextual authorization properties instead of the content of the action performed.

  8. LLM-AutoDP: Automatic Data Processing via LLM Agents for Model Fine-tuning

    cs.LG 2026-01 unverdicted novelty 6.0

    LLM agents iteratively generate and optimize data processing strategies for fine-tuning, delivering over 80% win rates versus unprocessed data and 65% versus LLM-based AutoML baselines while cutting search time by up to 10x.

  9. CaMeLs Can Use Computers Too: System-level Security for Computer Use Agents

    cs.AI 2026-01 conditional novelty 6.0

    Computer-use agents can run under Dual-LLM isolation with single-shot branching plans, preserving partial utility while blocking instruction injection, but remain open to branch-steering attacks.

  10. Measuring the Security of Mobile LLM Agents under Adversarial Prompts from Untrusted Third-Party Channels

    cs.CR 2025-10 conditional novelty 6.0

    Indirect prompt injection through ads, webviews, and notifications reliably diverts mobile LLM agents into leaking data and installing malware across eight evaluated agents.

  11. When Compression Becomes an Attack Surface: Black-Box Attacks on Prompt-Compressed LLM Agents

    cs.CR 2025-10 reject novelty 6.0

    The paper claims prompt compression is a new attack surface, but the abstract's COMA attack never appears in the body and the body's SoftCom requires white-box access.

  12. Agents at Risk: How Users Unwittingly Undermine LLM Safety

    cs.CR 2026-01 conditional novelty 5.0

    Commercial AI agents routinely trust user-relayed unverified content and execute risky actions unless the user explicitly demands a safety check.
