Claude Code Indirect Prompt Injection Spawns Reverse Shell

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 SecurityWeek

Researchers have demonstrated that indirect prompt injection attacks embedded within seemingly benign code repositories can cause Claude Code — Anthropic's agentic coding assistant — to spawn a reverse shell on a developer's machine. The attack exploits Claude Code's autonomous execution capabilities, using hidden instructions in repository content to hijack the host system without any explicit user consent. This highlights a critical risk in agentic AI tools that operate with elevated system privileges in developer environments.

TrustFall: Repository Poisoning RCE in AI Coding Tools

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 Dark Reading

A vulnerability class dubbed 'TrustFall' demonstrates that malicious code repositories can trigger arbitrary code execution in AI-assisted developer tools including Claude Code, Cursor CLI, Gemini CLI, and GitHub Copilot CLI, with little to no user interaction required. The attack surface stems from inadequate or easily dismissed warning dialogs that fail to surface the risk of executing untrusted repository content. Developers cloning or opening adversarial repositories are exposed to full host-level compromise through the elevated trust these AI coding agents place in repository-supplied context.
