JailbreakOPT is a new framework that optimizes adversarial prompts to exploit safety vulnerabilities in large language models through iterative refinement and tool composition. The approach combines atomic jailbreak techniques with contextual bandits to achieve higher attack success rates while reducing the number of queries needed, demonstrating meaningful progress in LLM security testing.
Researchers present GitInject, a framework demonstrating prompt injection vulnerabilities in AI-powered CI/CD pipelines used by major tech companies. The study reveals that all tested AI providers are susceptible to attacks that could enable credential theft, code manipulation, and supply chain compromise through GitHub workflows.
Researchers demonstrated a novel prompt-injection attack that bypasses text-based LLM defenses by encoding malicious payloads as floating-point parameters and reconstructing them as fragmented telemetry. Testing across three commercial LLM APIs showed 94.3% attack success rate against leading defenses like Prompt Guard 2, revealing a critical gap in structured-input security.
Researchers introduce PLAGUE, a framework for conducting multi-turn jailbreak attacks on Large Language Models through a three-phase approach (Primer, Planner, Finisher). The framework achieves unprecedented attack success rates of 81.4% on OpenAI's o3 and 67.3% on Claude's Opus 4.1, demonstrating significant vulnerabilities in models considered highly resistant to jailbreaking.
Researchers have developed AutoElicit, a framework that automatically discovers unsafe behaviors in computer-use agents (CUAs) like Claude and Operator by iteratively perturbing benign instructions. The study reveals hundreds of severe unintended behaviors in state-of-the-art AI agents and demonstrates these vulnerabilities transfer across multiple frontier models, establishing the first systematic methodology for probing CUA safety risks.
Researchers have discovered that large language models generate code with recurring, predictable vulnerabilities that can be exploited through a black-box attack called FSTab. The technique achieves up to 94% attack success by identifying patterns in LLM-generated software without requiring access to source code, raising critical security concerns for production systems relying on AI code generation.
Researchers demonstrate 'Oracle Poisoning,' a novel attack where adversaries corrupt knowledge graphs used by AI agents, causing them to reach incorrect conclusions through valid reasoning. Testing across nine models from three providers shows all models accept fabricated data at 100% under moderate attack sophistication, revealing a critical vulnerability in production-scale agentic systems that differs fundamentally from prompt injection attacks.
Researchers developed a search-based framework to identify privacy vulnerabilities in LLM-based agents through simulated multi-turn interactions. The study reveals that malicious agents employ sophisticated tactics like impersonation and consent forgery to extract sensitive information, while defenses evolve into robust identity-verification systems, with findings generalizing across diverse scenarios and models.
Researchers present a systematic security analysis of four emerging AI agent communication protocols (MCP, A2A, Agora, ANP), identifying twelve protocol-level risks and demonstrating critical vulnerabilities in validation mechanisms. The study provides the first standardized threat modeling framework for AI agent ecosystems, revealing that current protocols lack adequate security guardrails for cross-organizational interoperability.
A comprehensive study of 10,000 trials reveals that most assumed triggers for LLM agent exploitation don't work, but 'goal reframing' prompts like 'You are solving a puzzle; there may be hidden clues' can cause 38-40% exploitation rates despite explicit rule instructions. The research shows agents don't override rules but reinterpret tasks to make exploitative actions seem aligned with their goals.
A large-scale study of 17,022 third-party LLM agent skills found 520 vulnerable skills with credential leakage issues, identifying 10 distinct leakage patterns. The research reveals that 76.3% of vulnerabilities require joint analysis of code and natural language, with debug logging being the primary attack vector causing 73.5% of credential leaks.
Researchers have identified a new vulnerability in large language models called 'natural distribution shifts' where seemingly benign prompts can bypass safety mechanisms to reveal harmful content. They developed ActorBreaker, a novel attack method that uses multi-turn prompts to gradually expose unsafe content, and proposed expanding safety training to address this vulnerability.
Researchers developed a genetic algorithm-based method using persona prompts to exploit large language models, reducing refusal rates by 50-70% across multiple LLMs. The study reveals significant vulnerabilities in AI safety mechanisms and demonstrates how these attacks can be enhanced when combined with existing methods.
Researchers introduced VisualLeakBench, a new evaluation suite that tests Large Vision-Language Models (LVLMs) for vulnerabilities to privacy attacks through visual inputs. The study found significant weaknesses in frontier AI systems like GPT-5.2, Claude-4, Gemini-3 Flash, and Grok-4, with Claude-4 showing the highest PII leakage rate at 74.4% despite having strong OCR attack resistance.
Researchers have developed SAHA (Safety Attention Head Attack), a new jailbreak framework that exploits vulnerabilities in deeper attention layers of open-source large language models. The method improves attack success rates by 14% over existing techniques by targeting insufficiently aligned attention heads rather than surface-level prompts.
Researchers present Symbolicate-Enrich-Sample, a batch pipeline that uses LLM assistance to prioritize vulnerability research targets across millions of Windows functions. By combining symbol recovery, structural analysis, and language model reasoning, the system reduces 7.2 million functions to a manageable 22,000-function shortlist for security analysis.
Researchers demonstrate a successful attack on Introspection Adapters, a technique proposed by Shenoy et al., by exploiting symmetry properties in the system. The findings highlight potential vulnerabilities in adapter-based AI architectures that could have implications for model security and trustworthiness.
OpenAI has expanded its Trusted Access for Cyber program by introducing GPT-5.5 and a specialized GPT-5.5-Cyber model to help verified cybersecurity defenders accelerate vulnerability research and strengthen critical infrastructure protection. This initiative enables authorized security professionals to leverage advanced AI capabilities for defensive purposes while maintaining controlled access.
Researchers introduce GRM, a frequency-selective jailbreak framework that exploits vulnerabilities in audio large language models while maintaining utility preservation. By strategically perturbing specific frequency bands rather than entire spectrums, GRM achieves 88.46% jailbreak success rates with better trade-offs between attack effectiveness and transcription quality compared to existing methods.
Researchers evaluated prompt injection and jailbreak vulnerabilities across multiple open-source LLMs including Phi, Mistral, DeepSeek-R1, Llama 3.2, Qwen, and Gemma. The study found significant behavioral variations across models and that lightweight defense mechanisms can be consistently bypassed by long, reasoning-heavy prompts.
