## AI Guardian Security Gap: No Protection Against Prompt Injection Attacks
A critical security gap has been identified in the AI Guardian security framework. While the system effectively blocks secret leakage and unauthorized directory access, it currently provides zero detection or protection against prompt injection attacks. This oversight creates a direct pathway for malicious actors to manipulate AI behavior, potentially overriding safety guidelines and extracting sensitive information through carefully crafted user inputs.

The vulnerability centers on prompt injection, a technique where attackers embed malicious instructions within seemingly normal prompts or external content. This can take multiple forms, including indirect injection via files, direct user input designed to bypass controls, jailbreak attempts to disable AI constraints, and sophisticated data exfiltration schemes. AI Guardian's existing security layers—secret scanning with Gitleaks and directory blocking via .ai-read-deny markers—are completely blind to this class of attack, leaving a significant portion of the threat surface unmonitored and unprotected.

This gap represents a fundamental weakness in the AI security stack. Without prompt injection detection, organizations relying on AI Guardian are exposed to risks where AI agents could be coerced into performing unauthorized actions or divulging confidential data. The absence of this layer contradicts the tool's stated purpose as a comprehensive guardian, signaling a pressing need to expand its defensive capabilities to address the evolving tactics of AI-focused threat actors.
