CVE-2026-4348Network attack vector

Unauthenticated SQL injection via unparameterized limit

Published May 7, 2026 · Updated May 7, 2026

SQL injection in WPDeveloper BetterDocs Pro 3.7.0 and earlier allows remote attackers to read database data through unauthenticated AJAX requests. The get_current_letter_docs and docs_sort_by_letter handlers interpolate the limit POST value into SQL before $wpdb->prepare() parameterizes only other values. Exploitation requires the Pro-only Encyclopedia feature to be installed, activated, enabled, and exposed through the WordPress site.
