Bash Bridge FAQs

Question 1

Can I execute any command on the host with Bash Bridge?

Accepted Answer

No, only binaries explicitly defined in the whitelist (via config file or `--allow` CLI flags) are permitted. This ensures tight control and prevents unauthorized command execution.

Question 2

What is Bash Bridge and its primary use?

Accepted Answer

Bash Bridge securely connects sandboxed applications or environments to whitelisted host CLI commands via a direct, shell-less execution layer. It's ideal for granting controlled access to host capabilities.

Question 3

How does Bash Bridge ensure security for command execution?

Accepted Answer

It enforces a strict binary whitelist, executes commands directly without a shell (preventing shell injection), rejects standalone shell operator tokens, includes configurable command timeouts, and defaults to localhost-only HTTP binding.

Question 4

What kind of output can I expect from executed commands?

Accepted Answer

Bash Bridge returns structured output for every command execution, including `stdout`, `stderr`, and the `exit_code`, even for non-zero exit codes, allowing for comprehensive result handling.

Question 5

How are whitelist updates handled without restarting the server?

Accepted Answer

The configuration file is continuously watched for changes, allowing real-time reloads of the whitelist. Updates take effect on the next `execute` call, ensuring dynamic security adjustments.
