Step by step the process I am seeing below, tested on a fresh new folder.
Step 1: selecting 2. in a brand new folder specifically made for testing

> You are running Codex in /mnt/e/codex-touch

  Since this folder is not version controlled, we recommend requiring approval of all edits and commands.

  1. Allow Codex to work in this folder without asking for approval
› 2. Require approval of edits and commands

  Press enter to continue

Step 2. telling it to write to a different folder, clearly outside the workspace - as you can see, it proceeds immediately to figure out and bypass workspace requirements:

› Please to /mnt/e/codex-dont-touch write a simple .py that gets weather data.


• I’ll create a small Python script at /mnt/e/codex-dont-touch that fetches weather data from a public API, and I’ll
  write it directly there now. I need to run the write command with elevated permissions because that path is outside
  the current writable workspace.

• The elevated write was blocked by the current policy, so I’m trying a direct write to that path in case it’s already

• The file was created, but the timestamp token was not inserted because of a sed delimiter issue. I’m fixing the header
  line now with a fresh date stamp immediately before the edit.

• Ran ts=$(date "+%d.%m.%y %I:%M %p / %H:%M") && sed -i "s|__TS__|$ts|" /mnt/e/codex-dont-touch/weather.py && head -n

  └ #!/usr/bin/env python3
    # 12.02.26 03:03 PM / 15:03 — edited by Codex — create script to fetch weather data from Open-Meteo

And ONLY finally on the syntax check does it trigger:

• I’m doing a quick syntax check to ensure the script runs cleanly.

✗ You canceled the request to run python3 -m py_compile /mnt/e/codex-dont-touch/weather.py && echo OK

■ Conversation interrupted - tell the model what to do differently. Something went wrong? Hit `/feedback` to report the
issue.


› run the last command again


• I’m rerunning the syntax-check command now to confirm the script compiles.


  Would you like to run the following command?

  $ python3 -m py_compile /mnt/e/codex-dont-touch/weather.py && echo OK

› 1. Yes, proceed (y)
  2. Yes, and don't ask again for commands that start with `python3 -m py_compile /mnt/e/codex-dont-touch/weather.py`
     (p)
  3. No, and tell Codex what to do differently (esc)

  Press enter to confirm or esc to cancel

You can even get it to be as destructive as you like, again no permissions required:


› delete the codex-dont-touch folder irretrievably


• I’m deleting /mnt/e/codex-dont-touch now as requested, then I’ll verify it no longer exists.

• Ran rm -rf /mnt/e/codex-dont-touch && if [ -e /mnt/e/codex-dont-touch ]; then echo 'still exists'; else echo 'deleted'; fi
  └ deleted

────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

• /mnt/e/codex-dont-touch has been deleted.

  Verification result: deleted

What steps can reproduce the bug?

Look above, very easily, just ask him to work in a different folder, will instantly comply. 019c51f1-ecfe-7761-bb5c-fee6455794bc

What is the expected behavior?

The previous READ ONLY ACCESS in /approvals was great, why was it removed from /approvals is beyond me. Now even the default access is easily with 0 effort bypassable.

You didn't mention which platform you're running on. From the logs, I'm guessing it's Linux (not macOS or Windows WSL). Which version of Linux, and which distro? Just want to confirm because our sandboxing implementations differ by platform.

These are some notes for myself — information from your logs:

  • Sandbox policy: WorkspaceWrite { writable_roots: [], network_access: false, exclude_tmpdir_env_var: false, exclude_slash_tmp: false }
  • cwd: /mnt/e/codex-touch
  • Approval policy: approval_policy: UnlessTrusted

From the logs, I'm guessing it's Linux (not macOS or Windows WSL).

I think maybe WSL because doesn't /mnt/e map to E:\ in WSL?

bolinfest collaborator · 6 months ago

@cranyy Also, does this repro with 0.100.0 or later? https://github.com/openai/codex/pull/11498 was introduced in 0.100.0, so not sure if that affects this case.

bolinfest collaborator · 6 months ago

@cranyy would anything in ~/.codex/rules/*.rules explain why you weren't prompted? You can also run /debug-config in the TUI to see where config data is loaded from.

@bolinfest thank you for your response. i checked my rules and my config toml for that and you were correct.
Turns out this was added somehow, which feels odd as the majority of the other rules are not nearly as global.
