Drupal has patched several vulnerabilities – both moderately critical and critical – in two versions of its content management system platform.

Drupal fixed a handful of issues in version 7 and 8 of the content management system core engine that could have led to cache poisoning, social engineering attacks, and a denial of service condition.

Three vulnerabilities were patched Wednesday in the Drupal content management system’s core engine, two of which were rated critical.
