## Why `sandbox_permissions = "require_escalated"` is treated as an explicit request to approve the command and run it outside the filesystem/platform sandbox. Before this change, shell and unified exec still registered managed network approval context and could inject Codex-managed proxy state into the child process, which meant an approved escalated command could still hit a second network approval path. This PR makes that escalation boundary consistent: once a command is explicitly approved to run outside the sandbox, Codex does not also route that process through the managed network proxy. ## Security impact Command/filesystem sandbox approval now implies network approval for that command. If an untrusted command or script is allowed to run with `require_escalated`, its network calls are unsandboxed: Codex-managed network allowlists and denylists are not respected for that process, so the command can exfiltrate any data it can read. ## What changed - Skip managed network approval specs for `SandboxPermissions::RequireEscalated`. - Pass `network: None` into shell, zsh-fork shell, and unified exec sandbox preparation for explicitly escalated requests. - Strip Codex-managed proxy environment variables when `CODEX_NETWORK_PROXY_ACTIVE` is present, while preserving user proxy env when the Codex marker is absent. - Add regression coverage for the prepared exec request so the old behavior cannot silently reappear. ## Verification - `cargo test -p codex-core explicit_escalation` - `cargo clippy -p codex-core --all-targets -- -D warnings`

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.
