Descriptions

WordPress before 4.8.3 is affected by an issue where $wpdb->prepare() can create unexpected and unsafe queries leading to potential SQL injection (SQLi) in plugins and themes, as demonstrated by a "double prepare" approach, a different vulnerability than CVE-2017-14723.

WordPress en versiones anteriores a la 4.8.3 se ve afectado por un problema en el que $wpdb->prepare() puede crear consultas inseguras e inesperadas que podrían provocar una inyección SQL (SQLi) en plugins y temas, tal y como se ve en el enfoque "double prepare". Esta es una vulnerabilidad diferente a CVE-2017-14723.

Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform SQL injections and various Cross-Side Scripting (XSS) and Server-Side Request Forgery (SSRF) attacks, as well as bypass some access restrictions.
