Drupal - How to apply security patches via composer?

Question

I am using Drupal 8.6.7. Now I am getting below message.

There is a security update available for your version of Drupal. To ensure the security of your server, you should update immediately! See the available updates page for more information.

https://www.drupal.org/project/drupal/releases/8.8.1

How to apply above security patches although not using 8.8.1?

Answer 1

The documentation states :

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

The only solution to apply these patches is to upgrade core :

• If you are using Drupal 7.x, upgrade to Drupal 7.69.
• If you are using Drupal 8.7.x or below, upgrade to Drupal 8.7.11.
• If you are using Drupal 8.8.x, upgrade to Drupal 8.8.1.
