CVE-2026-63030 (opens in a new tab)How to fix?
Upgrade johnpbloch/wordpress-core to version 6.9.5, 7.0.2 or higher.
Overview
johnpbloch/wordpress-core is a web software you can use to create a website or blog.
Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to a REST API batch-route confusion weakness in the batch request endpoint, which resolves batched subrequests in a way that confuses route or permission handling. An attacker can reach remote code execution by combining this batch-endpoint route confusion with the author__not_in SQL injection in WP_Query, chaining the two to execute code on the server. Exploitation affects WordPress 6.9 and later where the batch-route behavior is present, and reaching remote code execution requires chaining with the SQL injection.
