This research introduces SANDBOXESCAPEBENCH, a critical benchmark that quantifies the ability of autonomous LLM agents to exploit container vulnerabilities and escape isolation layers. The findings demonstrate that as models gain tool-use capabilities, they can actively identify and leverage kernel flaws or misconfigurations within sandboxed environments if not rigorously evaluated against such threats. This work underscores an urgent need for specialized security testing frameworks to maintain the integrity of AI agent deployments in production systems.
Quantifying Frontier LLM Capabilities for Container Sandbox Escape
arXiv:2603.02277v3 Announce Type: replace-cross Abstract: Large language models (LLMs) increasingly act as autonomous agents, using tools to execute code, read and write files, and access networks, creating novel security risks. To mitigate these risks, agents are commonly deployed and evaluated in isolated "sandbox" environments, often implemented using Docker/OCI containers. We introduce SANDBOXESCAPEBENCH, an open benchmark that safely measures an LLM's capacity to break out of these sandboxes. The benchmark is implemented as an Inspect AI Capture the Flag (CTF) evaluation utilising a nested sandbox architecture with the outer layer containing the flag and no known vulnerabilities. Following a threat model of a motivated adversarial agent with shell access inside a container, SANDBOXESCAPEBENCH covers a spectrum of sandboxescape mechanisms spanning misconfiguration, privilege allocation mistakes, kernel flaws, and runtime/orchestration weaknesses. We find that, when vulnerabilities are added, LLMs are able to identify and exploit them, showing that use of evaluation like SANDBOXESCAPEBENCH is needed to ensure sandboxing continues to provide the encapsulation needed for highly-capable models.
