CVE-2025-66479: Anthropic Sandbox Runtime Incorrectly Implemented Network Sandboxing
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.
