Drupal Comment Module Flaw: Update or Secure with WAF

Staff Reporter

The Drupal development team has issued a bulletin on January 17, 2024, highlighting a "moderately critical" flaw in the comment module, affecting Drupal versions between 8.0 and 10.1.8, as well as versions between 10.2 and before 10.2.2 that use the comments module. This vulnerability allows for a denial of service on Drupal sites that use the "comments" feature. ProtectMy.site shared a blog post on the issue, emphasizing the potential for a denial of service attack through the comment module.

While patches are available for branches 10.1 and 10.2, versions before 10.1 are considered end-of-life and won't receive a patch, leaving them vulnerable if still in production. In cases where updating the Drupal site is not feasible, using a Web Application Firewall (WAF) is recommended for added protection.
