Description

The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-Forwarded-For' header in versions up to, and including, 1.4.14 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: Practical exploitation is constrained due to a 20-character storage limit.
