## Why The proxy matches allow and deny rules against normalized host strings. Scoped IPv6 literals can arrive in equivalent forms, such as `fd00::1%eth0`, `[fd00::1%eth0]`, or `[fd00::1%25eth0]`. Policy should canonicalize those spellings without erasing scope granularity: an unscoped rule like `fd00::1` should still cover scoped requests for that address, while a scoped rule like `fd00::1%eth0` should remain exact to that scope. ## What changed - preserve IPv6 scope IDs during host normalization and canonicalize `%25scope` to `%scope` - match policy against the exact normalized host plus the unscoped IP base for scoped literals - keep local-address explicit allow checks aligned with the same scoped/unscoped semantics - add focused coverage for scoped IPv6 normalization, scoped allow rules, and scoped deny rules in `network-proxy` ## Security impact A request cannot bypass a broad deny rule by adding an IPv6 scope suffix. At the same time, scoped policy remains precise: `deny=fd00::1%eth0` affects that scoped spelling without collapsing `fd00::1%eth1` onto the same key, and `allow=fe80::1%eth0` does not implicitly allow other scopes. ## Verification - `just fmt` - `cargo test -p codex-network-proxy` - `just fix -p codex-network-proxy` - `git diff --check` --------- Co-authored-by: Codex <noreply@openai.com> Co-authored-by: evawong-oai <evawong@openai.com>

npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
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
Install globally with your preferred package manager:
# 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
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
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.
