TREX is a code reviewer developed by Greptile that executes code and identifies errors during the review process. It enhances traditional code inspection methods by integrating code execution with pull request reviews.

Config files in repositories can execute code automatically when opened by development tools, potentially allowing attackers to run malicious code without the developer's awareness. Tools such as VS Code, Cursor, Claude Code, Gemini CLI, npm, Composer, and Bundler can read and act on these config files.

Micropython-wasm is an alpha package designed to run Python code in a sandbox using MicroPython and WebAssembly (WASM). It serves as a code execution sandbox plugin for Datasette Agent, named datasette-agent-micropython.

Using iTerm2, executing the command "cat readme.txt" can lead to arbitrary code execution. This vulnerability arises from iTerm2's legitimate features that inadvertently allow such exploits.

Sandboxing untrusted code is crucial for safely running AI-generated code, customer scripts on multi-tenant platforms, and RL training pipelines. Various technologies, including Docker containers, microVMs, and WebAssembly modules, provide different levels of isolation for executing potentially harmful code.
