MosaicLeaks: AI Agents Leak Sensitive Data in New Benchmark
Reported by Hugging Face Blog: MosaicLeaks: Can your research agent keep a secret?. Analysis and context written by TickrWire.
Hugging Face and ServiceNow reveal MosaicLeaks, a benchmark exposing vulnerabilities in AI research agents that inadvertently leak sensitive data during tool use.

- MosaicLeaks is a new benchmark to test AI research agents for data leakage vulnerabilities.
- Tests show many agents fail to sanitize outputs, risking exposure of sensitive data.
- The benchmark simulates real-world tool interactions (APIs, databases) where leaks may occur.
- Hugging Face and ServiceNow jointly developed the benchmark to address security gaps.
- Results underscore the need for stronger data protection in AI agent deployments.
Hugging Face and ServiceNow have jointly published MosaicLeaks, a new benchmark designed to test the security of AI research agents. The benchmark simulates scenarios where agents interact with tools (e.g., APIs, databases) and inadvertently expose sensitive or proprietary data. Early tests reveal that many agents fail to adequately sanitize outputs, risking data leaks. The findings highlight a critical gap in current AI agent frameworks, particularly for enterprise and research environments handling confidential information.
Developers must prioritize secure agent design to prevent accidental data leaks in tool interactions.
Enterprises using AI agents for sensitive workflows face heightened risk of proprietary data exposure.
Security flaws in AI agents could delay adoption in regulated industries, impacting investment timelines.
Students learning AI agent development should incorporate security best practices early in their work.
The benchmark raises awareness about the risks of AI agents mishandling confidential data in everyday tasks.
- AI research agent
- An AI system designed to autonomously perform research tasks, often interacting with external tools like APIs or databases.
- Data leakage
- The unintentional exposure of sensitive or proprietary information through system outputs or interactions.
- Benchmark
- A standardized test or dataset used to evaluate the performance, security, or capabilities of AI systems.
