The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'conversation' parameter in all versions up to, and including, 8.7.3 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. The action is gated only by a nonce that is localized into every public-facing page via wplocalizescript, rendering the nonce check ineffective as an access control barrier for unauthenticated users.

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 unauthenticated attackers to delete arbitrary chat session records from the wpbotuser and wpbotconversation tables, including chat history and conversation logs, by supplying a crafted userid value.

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 ragdocuments table and consuming the site owner's paid third-party AI API credits (OpenAI, Gemini, OpenRouter, or xAI).

The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'conversation' parameter in all versions up to, and including, 8.4.9 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. The AJAX nonce required to authenticate the save request is publicly emitted on every frontend page via wplocalizescript, making it freely obtainable by any anonymous visitor and removing any practical barrier to exploitation.

The WPBot Pro Wordpress Chatbot plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'qcwplatestupdatecheckpro' function in all versions up to, and including, 13.5.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create Simple Text Responses to chat queries.

The WPBot Pro Wordpress Chatbot plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the qcldopenaideletetrainingfile() function in all versions up to, and including, 13.6.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The WPBot Pro Wordpress Chatbot plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'qcldwpcfbfileupload' function in all versions up to, and including, 13.5.4. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. Note: The exploit requires thee ChatBot Conversational Forms plugin and the Conversational Form Builder Pro addon plugin.
