What issue are you seeing?

While developing a storage system in Rust and adding a fuzz test on one of its component, I started to get that security alert every several minutes, even as a response to the agent's output, not my prompt. Finally, after rephrasing my prompts as suggested by support, I got almost immediate alert.

What steps can reproduce the bug?

Uploaded thread: 01a01fc7-c7b4-70a3-93cc-2a0ab7392512

What is the expected behavior?

Fuzzing is a common way to increase stability and quality of a product, I don't expect to see these security alerts.

Additional information

No response

The issue identifies Codex CLI 0.148.0 on Linux but names no source file, test, or alert details beyond the doctor report. Start by reproducing the false-positive security alert and tracing the relevant CLI diagnostic entry point; done means the same valid setup no longer produces the alert, with a regression test covering it.
