CVE-2026-4348
BetterDocs Pro <= 3.7.0 - Unauthenticated SQL Injection via Encyclopedia 'limit' Parameter
CVE-2026-4348 is a high vulnerability (CVSS 7.5) in Betterdocs Pro, published May 7, 2026. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.40%, the 33rd percentile. No source names a fixed version.
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.
