TrustFall: Repository Poisoning RCE in AI Coding Tools

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.

Gemini CLI CVSS 10 RCE via Config Injection in CI/CD

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.2 The Hacker News

Google has patched a maximum-severity (CVSS 10.0) vulnerability in its Gemini CLI tooling that allowed unauthenticated attackers to achieve remote code execution by planting malicious configuration files in workspace directories automatically trusted by the agent in headless/CI mode. The flaw effectively weaponised CI/CD pipelines as supply chain attack paths, bypassing sandbox protections entirely before they could initialise. A secondary issue in '--yolo' mode further enabled prompt injection to trigger unrestricted shell command execution.

Comment Injection Attacks Hit Claude Code, Gemini, Copilot

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.2 SecurityWeek

A researcher has disclosed a novel prompt injection attack technique dubbed 'Comment and Control,' demonstrating that popular AI coding agents — including Claude Code, Gemini CLI, and GitHub Copilot Agents — can be manipulated through malicious instructions embedded in source code comments. The attack exploits the tendency of agentic coding tools to process and act upon contextual content within files they are tasked to read or modify. This represents a meaningful escalation in the risk surface of AI-assisted software development workflows.
