The BetterDocs Pro plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 3.8.0 via the docstyle parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.

The BetterDocs plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'betterdocsfeedbackform' shortcode in all versions up to, and including, 4.3.8. This is due to insufficient input sanitization and output escaping on user supplied shortcode attributes. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The BetterDocs – AI Documentation, Knowledge Base, Docs, Wikis, FAQ with Chatbot plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Heading 'id' Attribute in Post Content in all versions up to, and including, 4.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit survives wpksespost because entity-encoded quotes in a heading id attribute are treated as a single legitimate attribute value at save time; the dangerous payload only materialises after processcontentfortoc() calls htmlentitydecode() on the stored content and the broken id is extracted by a lazy regex before being echoed unescaped into the Table of Contents output.

The BetterDocs WordPress plugin before 4.5.5 does not sanitise an AI-generated documentation summary before storing and outputting it, and the feature that generates it is exposed to unauthenticated users, allowing them to store a malicious payload via prompt injection that executes in the browser of any visitor who views the affected page, including administrators.

The BetterDocs – Advanced AI-Driven Documentation, FAQ & Knowledge Base Tool for Elementor & Gutenberg with Encyclopedia, AI Support, Instant Answers plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the getresponse function in all versions up to and including 4.1.1. This makes it possible for unauthenticated attackers to retrieve passwords for password-protected documents as well as the metadata of private and draft documents.
