CVE-2026-40762Network attack vector

Unauthenticated SQL injection via nonnumeric user loader keys

Published Jun 15, 2026 · Updated Jun 15, 2026

SQL injection in WPGraphQL before 2.11.1 allows remote attackers to disclose database data through unauthenticated GraphQL requests. The user data loader accepts nonnumeric loader keys for a database lookup instead of rejecting them before query construction. A crafted request must reach the site's GraphQL endpoint; published metrics bound the consequence to data disclosure and limited service degradation.
