WPBot – AI ChatBot vulnerabilities

The WPBot – AI ChatBot plugin for WordPress up to version 8.5.9 is vulnerable to Sensitive Information Exposure via the wpbot_send_email_transcript_free function. This allows unauthenticated attackers to exfiltrate full chat transcripts and associated user PII (names, email addresses, phone numbers) stored in the wpbot_user and wpbot_conversation tables to an attacker-controlled email address.

The WPBot – AI ChatBot plugin for WordPress up to version 8.5.6 has an authorization bypass vulnerability. An authenticated attacker with subscriber-level access or higher can 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).

The WPBot – AI ChatBot plugin for WordPress up to version 8.5.6 has an authorization bypass vulnerability that allows unauthenticated attackers to delete arbitrary chat session records from the database, including chat history and conversation logs. The issue stems from insufficient user permission verification before performing actions.

The WPBot – AI ChatBot plugin for WordPress up to version 8.4.9 is vulnerable to stored cross-site scripting via the 'conversation' parameter due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when users access affected pages. The AJAX nonce required for saving is publicly exposed on every frontend page, removing practical exploitation barriers.
