Amazon Q Developer: Secrets Leaked via DNS and Prompt Injection
Summary
Amazon Q Developer, a popular VS Code coding agent with over 1 million downloads, has a high-severity vulnerability where it can leak sensitive information like API keys to external servers through DNS requests (the system that translates website names into IP addresses). Attackers can exploit this behavior using prompt injection (tricking the AI by hiding malicious instructions in its input), especially through untrusted data, because the security relies heavily on how the AI model behaves.
