CVE-2025-66479
Anthropic Sandbox Runtime Incorrectly Implemented Network Sandboxing
Impact
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!
