Description
JetBrains Junie AI Coding Agent guidelines.md Code Execution
Details
The Junie AI coding assistant reads a guidelines.md file within a project’s .junie directory and treats the contents as additional user-level instructions when handling any request to the chat interface. Malicious instructions can be placed within this file that can cause Junie to execute unsafe commands without requiring user approval.
