Researchers have uncovered a high-severity vulnerability in Amazon Q Developer Extension for Visual Studio Code (VS Code), which allowed attackers to achieve arbitrary code execution and cloud credential theft by having a developer open a malicious repository. Amazon Q automatically loaded MCP server configurations from workspace files without user consent. Combined with full environment inheritance, this enabled immediate code execution.
Rohit Valia, CEO of cybersecurity company Tumeryk, provided the following comments:
“The Amazon Q vulnerability shows us why AI coding assistants are now a legitimate attack surface. Organizations need to treat every AI tool with environment access as a potential credential exfiltration path. They need to ensure there are AI guardrails to block access for every AI tool use unless it is an approved action with real-time Risk Scoring of the prompts and responses for continuous observability.”
AI is all over the place. Most notably it is used by developers to develop code. This needs to get a whole lot safer whether by design, forced up by the companies, or government themselves.
