Description
The user password reset form in Drupal 8.x before 8.2.3 allows remote attackers to conduct cache poisoning attacks by leveraging failure to specify a correct cache context.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| drupal/core | >= 8.0, < 8.2.3 |
8.2.3 |
| drupal/drupal | >= 8.0, < 8.2.3 |
8.2.3 |
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 → 8.2.3
- composer
composer require drupal/core:^8.2.3
drupal/drupal Packagist → 8.2.3
