    Anthropic Sandbox Runtime Incorrectly Implemented Network Sandboxing

    CVE-2025-66479 · GHSA-9gqj-5w7c-vx47

    Affected
    • npm @anthropic-ai/sandbox-runtime < 0.0.16
    Fixed in
    0.0.16· Vendor fix available
    Issue
    Due to a bug in sandboxing logic, sandbox-runtime did not properly enforce a network sandbox if the sandbox policy did not configure any allowed domains. This could allow sandboxed code to make network requests outside of the sandbox. A patch for this was released in v0.0.16. Thank you to https://github.com/bendrucker for reporting this issue!

    Recommended action: Upgrade to 0.0.16 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
