CVE-2026-2363Network attack vector

Authenticated SQL injection via shortcode order_by attribute

Published Mar 4, 2026 · Updated Mar 4, 2026

SQL injection in Chad Butler WP-Members 3.5.5.1 and earlier allows remote authenticated users to read database data via a crafted shortcode. The wpmem_user_membership_posts shortcode passes its untrusted order_by attribute into an insufficiently escaped and unprepared SQL query. Contributor-level post-editing access is required, and injected query fragments can extract sensitive database information.
