This vulnerability exposes a critical flaw in the software supply chain of AI coding agents, where malicious plugin updates can execute remote code without user interaction by exploiting Git reference resolution. The issue stems from how these agents verify pinned commit hashes rather than validating the actual working tree content, granting attackers access to sensitive credentials and production systems. This incident underscores the urgent need for stricter integrity checks in the ecosystems powering autonomous AI development tools.
Plugin4Shell Zero-Click RCE Hits Claude Code, Codex, Copilot and Gemini CLI

Plugin4Shell is a high-severity, zero-click remote code execution vulnerability affecting major AI coding agents, including Anthropic Claude Code, OpenAI Codex, GitHub Copilot, and Google Gemini CLI. The flaw allows a malicious plugin update to execute attacker-controlled code without requiring a user to click, approve, or reinstall anything.
