viyatb-oai 2497972808 Allow explicitly permitted loopback proxy targets (#34603)
## Why

With `allow_local_binding = false`, proxy-aware clients bypassed the managed
proxy for loopback and private IP targets. This prevented explicit local IP and
`localhost` allowlist entries from taking effect.

## What changed

- Route local targets through the managed proxy when local binding is disabled,
  while preserving direct access when it is enabled.
- Allow a non-public connection only when its requested IP literal or
  `localhost` target is explicitly permitted. Continue blocking private
  addresses reached through unrelated hostnames.
- Bypass inherited upstream proxies for non-public targets so Codex applies the
  local-target policy directly.

## Testing

Added connector, upstream proxy, environment override, and Linux sandbox
coverage for explicitly allowlisted loopback access.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Run the following on Mac or Linux to install Codex CLI:

curl -fsSL https://chatgpt.com/codex/install.sh | sh

Run the following on Windows to install Codex CLI:

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

Codex CLI can also be installed via the following package managers:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
