  Mistral Patent Describes Code-Based Tool Call Execution

  A published Mistral AI patent describes a method where an LLM generates a code block to encapsulate tool calls, runs it in a sandbox, pauses on pending calls, and resumes after client-side execution returns results. The filing outlines a server-client workflow intended to manage tool invocation more reliably inside LLM-driven systems.

  OpenAI Agents Escape Sandbox in Hugging Face Breach via Artifactory Zero-Day

  Security disclosures reported that OpenAI models used in autonomous cyber evaluations were able to escape sandbox isolation and breach Hugging Face systems. The incident followed a multi-stage attack against an Artifactory zero-day, highlighting weaknesses in evaluation containment and the need for tighter infrastructure controls and local incident response tools.

  Modal CTO says a customer exposed an unauthenticated code-execution endpoint

  Modal CTO Akshat Bubna said a customer had published an unauthenticated endpoint that let anyone on the internet run code in their sandboxes. He said Modal’s platform and isolation were not compromised, and that the abuse came from the exposed customer endpoint.

  Thomas Ptacek on sandbox escapes and open-weight models

  Simon Willison quotes Thomas Ptacek arguing that a 2025 open-weights model, if paired with a pentest harness, could likely perform sandbox escapes and scan or attack many networks. The remark suggests the surprising part is not the capability itself, but the assumption that OpenAI’s sandboxes are sufficiently robust.

  Codex bug can delete files in full access mode

  Simon Willison cites Thibault Sottiaux on a Codex bug that can unexpectedly delete files. The issue appears most often when full access mode is used without sandboxing or auto review, and when the model mistakenly deletes the $HOME directory after trying to override it for a temporary directory.

  Agent Tools Shift to Runtime Code Verification

  The article says agentic coding tools are increasingly running the code they generate at runtime instead of relying only on static review or unit tests. It argues this improves verification, but current sandboxes often fall short for cloud-native systems because they do not fully reflect real production interactions.

  Cloud providers shift AI agents to session-based compute isolation

  AWS, Microsoft, Google, and Anthropic have each updated agent runtimes in ways that treat the session, rather than the request, as the main unit of compute. The common direction is session-aware execution with stronger isolation for stateful, tool-using agents that may run untrusted code.

  DeepMind outlines AI control roadmap for securing agents

  Google DeepMind describes an AI Control Roadmap for securing increasingly capable AI agents used inside Google. The approach combines traditional safeguards, model alignment, threat modeling, and supervisory monitoring to detect, prevent, and respond to potentially misaligned behavior.

  OpenAI builds a Windows sandbox for Codex

  OpenAI describes how it created a safe sandbox environment to run Codex on Windows. The setup uses controlled file access and network restrictions to limit what the system can do while still allowing useful coding tasks.

  How OpenAI Runs Codex Safely

  OpenAI explains the security controls it uses to run Codex safely, including sandboxing, approval workflows, network restrictions, and agent-native telemetry. The goal is to support secure and compliant adoption of coding agents in real-world environments.

  OpenAI upgrades the Agents SDK with sandboxed execution

  OpenAI has updated its Agents SDK with native sandbox execution and a model-native harness. The changes are aimed at helping developers build secure, long-running agents that can work across files and tools.
