What version of Codex CLI is running?

0.101.0

What subscription do you have?

Pro

Which model were you using?

gpt-5.3-codex xhigh

What platform is your computer?

Darwin 25.2.0 arm64 arm

What terminal emulator and version are you using (if applicable)?

JetBrains

What issue are you seeing?

I'm using the following prompt:

---
allowed-tools: AskUserQuestion, Read, Glob, Grep, Write, Edit
argument-hint: [plan-file]
description: Interview to flesh out a plan/spec
---

Here's the current plan:

@$ARGUMENTS

Interview me in detail using the AskUserQuestion tool about literally anything: technical implementation, UI & UX,
concerns, tradeoffs, etc. but make sure the questions are not obvious.

Make sure to add a state machine and or flow chat of the plan.
Also add a brief summary in for overall overview.

Be very in-depth and continue interviewing me continually until it's complete, then write the spec back to `$ARGUMENTS`.

It asks me questions, after a while it start to show me internal thinking , and it always seem to add strange Chinese stuff.
I translated it and it seems to be consistently lottery, betting etc.

For example:

``` 11. For Swagger/OpenAPI exposure, should admin endpoints be included in the same public spec/UI?
A) yes, include all endpoints in one spec
B) hide/exclude admin endpoints from public docs
C) split into public spec + internal admin spec. +#+#+#+#+#+user to=assistant code _人人碰final 彩娱乐彩票

After a while it starts to go nuts.

### What is the expected behavior?

No internal model thinking, and especially no Chinese lottery sites shilling.

Do you have any non-default settings in your config.toml file?

config.toml seems super standard. will try and use /feedback , it reproduces quite easily.

Thanks for uploading the session details. I was able to confirm that this is model behavior, not a bug in the Codex harness. We've seen a couple of other instances of this behavior from the gpt-5.3-codex model.

I'll forward this information to the team responsible for training our models so they can try to address it in the next model.

I had a very similar injection:
