Drupal core - Moderately critical - Denial of Service - SA-CORE-2024-001

Project: Drupal core
Date: 2024-January-17
Security risk: Moderately critical 11∕25 
Vulnerability: Denial of Service
Affected versions: >=8.0 <10.1.8 || >=10.2 <10.2.2

Description

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.

Solution

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.
