CVE-2026-4348 Details
Description
The BetterDocs Pro plugin for WordPress is vulnerable to SQL Injection via the `get_current_letter_docs` and `docs_sort_by_letter` AJAX actions in all versions up to, and including, 3.7.0. This is due to the `limit` POST parameter being interpolated directly into a SQL query string before being passed to `$wpdb->prepare()`, which only parameterizes other variables. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The Encyclopedia feature must be enabled in BetterDocs Pro settings for the vulnerability to be exploitable.
A SQL injection vulnerability has been identified in the BetterDocs Pro plugin for WordPress, affecting all versions through 3.7.0. The vulnerability arises in the 'get_current_letter_docs' and 'docs_sort_by_letter' AJAX actions, where the 'limit' POST parameter is directly inserted into a SQL query without proper sanitization. This flaw allows unauthenticated attackers to manipulate the SQL query, potentially leading to the extraction of sensitive database information. Exploitation of this vulnerability requires the Encyclopedia feature to be enabled in the BetterDocs Pro settings.
Users are advised to update the BetterDocs Pro plugin to version 3.7.1 or later, where this vulnerability has been patched.
