The Comment module allows users to reply to comments. In certain cases, an attacker could make comment reply requests that would trigger a denial of service (DOS).
Sites that do not use the Comment module are not affected.
Install the latest version:
- If you are using Drupal 10.2, update to Drupal 10.2.2.
- If you are using Drupal 10.1, update to Drupal 10.1.8.
All versions of Drupal 10 prior to 10.1 are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.)
Drupal 7 is not affected.
