Summary
The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.4.6. This is due to the `getCurrentTaskResults()` method in `modules/workspace/controller.php` being accessible without authentication or authorization checks. The method is not included in the workspace controller's `getNoncedMethods()` array, the base `getPermissions()` returns an empty array, and all AJAX actions are registered with `wp_ajax_nopriv_` hooks (`classes/frame.php:282`). When tasks are created via features like the Bulk Post Generator, the task parameters — including the OpenAI API key in plaintext, AI prompts, keywords, and full AI model configuration — are stored in the database and returned in the JSON response. This makes it possible for unauthenticated attackers to enumerate sequential task IDs and retrieve sensitive configuration data including API keys.
