SQL Injection in BetterDocs WordPress Plugin

Publication date: 2026-07-10

Last updated on: 2026-07-10

Assigner: Wordfence

Description
The BetterDocs – AI Documentation, Knowledge Base, Docs, Wikis, FAQ with Chatbot plugin for WordPress is vulnerable to generic SQL Injection via the 'lang' parameter in all versions up to, and including, 4.6.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires a supported multilingual plugin (WPML, Polylang, qTranslate, Weglot, or TranslatePress) to be active on the site, as the vulnerable code path is gated by Helper::is_multilingual_active().

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The BetterDocs plugin for WordPress has a vulnerability known as a generic SQL Injection through the 'lang' parameter. This happens because the plugin does not properly escape user input and does not sufficiently prepare the SQL queries. As a result, authenticated users with custom-level access or higher can inject additional SQL commands into existing queries.

This vulnerability only affects sites that have a supported multilingual plugin active, such as WPML, Polylang, qTranslate, Weglot, or TranslatePress, because the vulnerable code is only executed when such a plugin is detected.

Impact Analysis

An attacker with authenticated access at custom-level or above can exploit this vulnerability to append additional SQL queries to existing ones. This can be used to extract sensitive information from the database.

The impact is rated with a CVSS base score of 6.5, indicating a medium severity with high confidentiality impact but no impact on integrity or availability.

Compliance Impact

The vulnerability allows authenticated attackers to perform SQL Injection attacks that can extract sensitive information from the database. This exposure of sensitive data could potentially lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require the protection of personal and sensitive information.

However, the provided information does not explicitly detail the impact on compliance with specific standards or regulations.
