Microsoft researchers detailed SymJack, a symlink-hijack RCE affecting six coding agents, and TrustFall, which impacts Claude Code, Cursor, Gemini CLI, and GitHub Copilot (Microsoft Security). These join Semantic Kernel prompt-injection-to-host-RCE flaws. The local coding agent is now a prime attack surface, not a sandboxed toy. Audit filesystem and symlink handling in anything you run with shell access.
