Vulnerability Title
WPBot <= 8.5.6 - Missing Authorization to Authenticated (Subscriber+) Arbitrary RAG Document Re-Sync via ajax_rag_manual_sync() Function
Source: CVE Program / CVE List V5
Vulnerability Description
The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 8.5.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to trigger arbitrary re-embedding of stored RAG documents, modifying the rag_documents table and consuming the site owner's paid third-party AI API credits (OpenAI, Gemini, OpenRouter, or xAI).
