Lack of domain validation in Druple core
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Packagist | drupal/core | >= 8.0.0, < 9.3.19 | 9.3.19 |
| Packagist | drupal/core | >= 9.4.0, < 9.4.3 | 9.4.3 |
Details
As written in the advisory (Markdown source, shown as plain text).
The Media oEmbed iframe route does not properly validate the iframe domain setting, which allows embeds to be displayed in the context of the primary domain. Under certain circumstances, this could lead to cross-site scripting, leaked cookies, or other vulnerabilities.
Drupal 7 core does not include the Media module and therefore is not affected.
