Executive Summary
Research shows decades-old Bash shell tricks bypass safeguards in most open source AI coding agents, turning malicious repos into supply chain vectors.
What Happened
Decades-old Bash shell tricks can bypass safeguards in most open source AI coding agents, potentially turning malicious repositories into supply chain attack vectors. The post Decades-Old Bash Tricks Expose AI Coding Agents to Supply Chain Attacks appeared first on SecurityWeek .
Vulnerability / Attack Technique
Command safeguard bypass in AI coding agents
Technical Mechanism
As reported, shell syntax defeats agents' command filtering.
AI Security Category
LLM06:2025 Excessive Agency
Part of the AI Agent Excessive Agency topic.
Relevant Frameworks
RealGround Analysis
Command allowlists by string matching are weak. RealGround analysis: sandbox agents instead of filtering commands.
Recommended Controls
- Run coding agents in sandboxes
- Avoid auto-approve modes on untrusted repos
