feat: whitelist some commands

[0xbrayo]

Important

Adds a whitelist for shell commands in execute_shell() to restrict execution and require confirmation for non-whitelisted commands.

• Security:
  • Adds a whitelist for shell commands in execute_shell() to restrict execution to ls, stat, cd, cat, pwd, echo.
  • Uses regex to parse commands and checks against the whitelist.
  • Requires user confirmation for non-whitelisted commands if ask is true.
• Misc:
  • Updates message formatting in execute_shell() to indicate if a command is whitelisted.

@ErikBjare Do I need to configure something on my end to fix these tests? I see one needs a OPENAI_KEY. They seem to be working on the other PRs though.

[ErikBjare]

Ah yes, since the keys are secret you don't have access to them when you trigger the job. Not sure what's the easiest way to work around this.

The logs contain Secret source: None

Weird that it worked for other PRs? It kinda shouldn't?

[ErikBjare]

I don't think it worked in other PRs either:

• feat: add platform info to the system prompt #171
• tests: update models to provider/model format #141

[ErikBjare]

Anyone with collaborator access to this repository can use these secrets and variables for actions. They are not passed to workflows that are triggered by a pull request from a fork.

I added you as a collaborator (invite sent), but you might have to set the secrets in your forked repo.

Sorry I meant it seems to be working on your PRs

  There's a typo in the f-string formatting. The empty string should be replaced with double quotes to avoid syntax errors.

@ErikBjare I set the both openai and anthropic api keys in my repo secrets. But the errors are still there :(

• Draft comment:
  The regex used for command parsing does not account for control flow statements like if, for, while, etc. This could lead to security issues if such commands are executed without confirmation. Consider enhancing the regex or adding additional checks to handle these cases.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  The comment is relevant to the changes made in the diff, specifically the introduction of a regex to parse commands. The concern about control flow statements is valid, as they can introduce security risks if not handled properly. The comment provides a clear suggestion to enhance the regex or add checks, which is actionable.
  The comment assumes that control flow statements are a security risk without confirmation. It might be speculative unless there's evidence that these statements are indeed a risk in this context.
  Control flow statements can indeed be a security risk if they allow execution of unintended commands. The comment is providing a precautionary measure, which is reasonable given the context of executing shell commands.
  The comment is relevant and provides a valid concern about potential security issues with control flow statements. It suggests an actionable improvement to the code.

@ErikBjare I think this is ready, do I merge? The list of whitelisted commands could be extended but that can be done later.

[ErikBjare]

Sure, but ask for a review first next time :)

[0xbrayo]

I tested the regex extensively but I guess it's the most unpredictable bit here.

You should compile this regex
