Title: LoopTrap: Termination Poisoning Attacks on LLM Agents

Abstract:
arXiv:2605.05846v1 Announce Type: cross Abstract: Modern LLM agents solve complex tasks by operating in iterative execution loops, where they repeatedly reason, act, and self-evaluate progress to determine when a task is complete. In this work, we show that while this self-directed loop facilitates autonomy, it also introduces a critical risk: by injecting malicious prompts into the agent's context, an adversary can distort the agent's termination judgment, making it believe the task remains inc
