CVE-2026-6639: AI Chatbot & Workflow Automation by AIWU <= 1.4.6 - Missing Authorization to Unauthenticated Sensitive Information Exposure
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 wpajaxnopriv 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.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Upgrade
Upgrade
wordpress/Ai Chatbot & Workflow Automation by AIWUto a version that resolves this vulnerability.Fixed in 1.4.6 - Compensating control
If you cannot patch immediately, restrict access to the affected WordPress AJAX endpoints (those registered with `wp_ajax_nopriv_` hooks, e.g., in `classes/frame.php:282`) so unauthenticated users cannot call them and enumerate task IDs.
- Operational
Rotate any exposed secrets after exploitation, including OpenAI API keys stored in plaintext in task parameters, and review/clear any task records that may have had sensitive data returned.
