10.1.8- Upgrade drupal/core to this version or later
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.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |

| drupal/core | >= 8.0.0, < 10.1.8 |
10.1.8 |
| drupal/core | >= 10.2.0, < 10.2.2 |
10.2.2 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
drupal/core Packagist → 10.1.8
