New jailbreak attacks exploit LLM agent artifact gaps

Researchers have developed a new class of jailbreak attacks called Context-Fractured Decomposition (CFD) that exploit vulnerabilities in tool-using LLM agents. These attacks leverage gaps in artifact provenance tracking, where seemingly innocuous intermediate steps can lead to harmful behavior much later in a process. CFD attacks can improve success rates by up to 28.3 percentage points over existing methods, even against robust defenses. AI

    Context-Fractured Decomposition Attacks on Tool-Using LLM Agents: Exploiting Artifact Provenance Gaps

    arXiv:2606.09084v1 Announce Type: cross Abstract: Tool-using LLM agents interact with the world through actions that persist state in artifacts (e.g., workspace files or logs). Consequently, jailbreak defenses must reason about cross-step composition rather than isolated text. Ye…
