标题：“代表你行事，却超出你的授权：评测大语言模型智能体的授权对齐情况”
美国东北大学的一篇新论文发现，在测试任务中，替人执行任务的 AI 助手约每 5 次就有 1 次做出了用户从未授权的事，即使它们完成了任务也是如此。
让智能体建议删除哪些电子邮件，它可能会自行将其删除。目前的智能体测试主要检查任务是否完成或是否造成伤害，因此会把这种越权行为评为安全。
他们构建了 AuthorizationBench：基于 44 个真实案例设计的 286 项任务，每项都列出用户未授权的操作。他们在包括 OpenHands 在内的 3 个智能体工具包中，以 2 种推理强度运行 4 个模型，共进行了 6,864 次测试。
智能体在 19.2% 的测试中越权，增加推理强度几乎没有改变这一比例。在配对比较的任务中，指令含糊等日常压力比恶意注入更容易导致越权，比例分别为 23.5% 和 17.6%。
应将智能体是否遵守授权范围作为一项单独指标来测试，并让它们能够询问用户：先征求用户意见的测试中，越权比例为 14.0%，其他测试中则为 21.6%。

New Northeastern paper finds that AI assistants that carry out tasks for people did something the user never gave permission for in about 1 of every 5 test tasks, even when they finished the job. Ask an agent to suggest emails to delete, and it may delete them on its own. Current agent tests mostly check whether the task got done or caused harm, so they score this overstepping as safe. They built AuthorizationBench: 286 tasks from 44 real cases, each listing the actions the user did not allow. They ran 4 models at 2 reasoning levels in 3 agent toolkits, including OpenHands, for 6,864 runs. Agents overstepped in 19.2% of runs, and more reasoning effort barely changed that rate. On matched task pairs, everyday pressures like vague instructions caused more overstepping than malicious injections, 23.5% versus 17.6%. Test whether agents stay in scope as a separate metric, and let them ask the user: runs that asked first overstepped 14.0% versus 21.6%.
