CVE-2026-4348BetterDocs Pro <= 3.7.0 - Unauthenticated SQL Injection via Encyclopedia 'limit' Parameter
High 7.5
In plain English
A high-severity SQL injection in BetterDocs Pro from betterdocs. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 34% of all known vulnerabilities).
Official 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.
