616 Network access is granted for each host, not for each operation. The sandbox can send any request to an allowed host, including uploads such as `git push` and package publishing, with any credential the command supplies. If the agent processes untrusted input (repository files, fetched web content, or third-party tool output), a successful prompt injection could use an allowed host to copy files out of the sandbox. To reduce this risk, set the `bash` tool's [permission policy](https://platform.claude.com/docs/en/managed-agents/permission-policies) to `always_ask` or `auto`. If the environment does not specify `packages` (csharp, go: `Packages`), you can instead leave `allow_package_managers` (java, php: `allowPackageManagers`; csharp, go: `AllowPackageManagers`) set to `false` and list only the hosts your agent needs in `allowed_hosts` (java, php: `allowedHosts`; csharp, go: `AllowedHosts`).
