CVE-2021-24403Public exploitNetwork attack vector

Authenticated SQL injection via unvalidated order identifier

Published Sep 20, 2021 · Updated Aug 3, 2024

SQL injection in WordPress Page Contact 1.0 allows remote authenticated users to execute crafted database queries through the Orders page. The Orders functionality inserts the untrusted order_id parameter into an SQL statement without sanitization, escaping, or validation. Contributor-level access is sufficient, and the published proof of concept confirms attacker-controlled query execution through a time delay.
