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.
Updated 2022-07-20 19:45 UTC to indicate that this only affects Apache web servers.
Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010).
Under certain circumstances, the Drupal core form API evaluates form element access incorrectly. This may lead to a user being able to alter data they should not have access to.
No forms provided by Drupal core are known to be vulnerable. However, forms added through contributed or custom modules or themes may be affected.
In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system.
Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability.
This module enables you to generate print versions of content.
Some installations of the module make use of the dompdf/dompdf third-party dependency.
Security vulnerabilities exist for versions of dompdf/dompdf < 2.0.0
This module enables you to create and manage a version of taxonomy based on configuration entities instead of content. This allows the terms, vocabularies, and their structure to be exported, imported, and managed as site configuration.
The module doesn't sufficiently check access for the edit and delete operations. Users with "access content" permission can edit or delete any term. The edit form may expose term data that users could not otherwise see, since there is no term view route by default.
The Lottiefiles Field module enables you to integrate the lottiefiles features into your page.
The module does not sufficiently filter user-provided text on output, resulting in a Cross-Site Scripting (XSS) vulnerability.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission to create or edit content that has lottiefiles fields.
In Drupal 9.4 and higher, drupal/core-recommended allows patch-level vendor updates
The drupal/core-recommended metapackage now allows patch-level updates for Composer dependencies. This means that site owners using drupal/core-recommended can now install most Composer dependency security updates themselves, without needing to wait for an upstream release of Drupal core that updates the affected package.
