Critical AI Prompt Injection Vulnerability Found in Go DataTable Plugin Code

A security review of the `ai_plugin.go` code has uncovered multiple critical vulnerabilities, with a prompt injection flaw posing the most immediate and severe risk. The plugin directly embeds user-controlled JSON data into AI prompts without any sanitization, creating a direct path for attackers to manipulate the AI's behavior. This design flaw could allow malicious actors to inject instructions, exfiltrate data, or cause other unintended consequences by crafting specific JSON payloads.

The vulnerability is located in the `buildTablePrompt` function, where unsanitized JSON is passed directly to the AI. The reviewer's analysis indicates the code lacks basic validation to ensure the input is legitimate JSON, let alone safe for inclusion in a prompt. The suggested fix involves implementing a `sanitizeJSONForPrompt` function that first validates the JSON structure and then scrubs dangerous patterns, such as triple backticks, which are common in prompt injection attacks. This oversight represents a fundamental failure in secure coding practices for AI-integrated applications.

If unpatched, this vulnerability exposes any application using this plugin to significant operational and data security risks. The presence of such a basic flaw in code handling AI interactions raises serious questions about the development and review processes for this component. It signals a pressing need for comprehensive security audits of similar AI plugin architectures, as the integration of untrusted user input with large language models remains a high-risk attack surface that many teams may still be underestimating.
