Drupal before 7.58, 8.x before 8.3.9, 8.4.x before 8.4.6, and 8.5.x before 8.5.1 allows remote attackers to execute arbitrary code because of an issue affecting multiple subsystems with default or common module configurations.

A jQuery cross site scripting vulnerability is present when making Ajax requests to untrusted domains. This vulnerability is mitigated by the fact that it requires contributed or custom modules in order to exploit. For Drupal 8, this vulnerability was already fixed in Drupal 8.4.0 in the Drupal core upgrade to jQuery 3. For Drupal 7, it is fixed in the current release (Drupal 7.57) for jQuery 1.4.4 (the version that ships with Drupal 7 core) as well as for other newer versions of jQuery that might be used on the site, for example using the jQuery Update module.

Drupal 8 before 8.2.8 and 8.3 before 8.3.1 allows critical access bypass by authenticated users if the RESTful Web Services (rest) module is enabled and the site allows PATCH requests.

A 3rd party development library including with Drupal 8 development dependencies is vulnerable to remote code execution. This is mitigated by the default .htaccess protection against PHP execution, and the fact that Composer development dependencies aren't normal installed. You might be vulnerable to this if you are running a version of Drupal before 8.2.2. To be sure you aren't vulnerable, you can remove the <siteroot>/vendor/phpunit directory from your production deployments

Some administrative paths in Drupal 8.2.x before 8.2.7 did not include protection for CSRF. This would allow an attacker to disable some blocks on a site. This issue is mitigated by the fact that users would have to know the block ID.

When adding a private file via the editor in Drupal 8.2.x before 8.2.7, the editor will not correctly check access for the file being attached, resulting in an access bypass.

The transliterate mechanism in Drupal 8.x before 8.2.3 allows remote attackers to cause a denial of service via a crafted URL.

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.

The taxonomy module in Drupal 7.x before 7.52 and 8.x before 8.2.3 might allow remote authenticated users to obtain sensitive information about taxonomy terms by leveraging inconsistent naming of access query tags.

Cross-site request forgery (CSRF) vulnerability in the Content Lock module for Drupal allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.

The Contact Forms module 7.x-1.x before 7.x-1.2 for Drupal does not specify sufficiently restrictive permissions, which allows remote authenticated users with the "access the site-wide contact form" permission to modify the module settings via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the Glossary module 6.x-1.x before 6.x-1.8 for Drupal allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to "taxonomy information."

Cross-site scripting (XSS) vulnerability in the aberdeen_breadcrumb function in template.php in the Aberdeen theme 6.x-1.x before 6.x-1.11 for Drupal, when set to append the content title to the breadcrumb, allows remote attackers to inject arbitrary web script or HTML via the content title in a breadcrumb.

Cross-site request forgery (CSRF) vulnerability in the Take Control module 6.x-2.x before 6.x-2.2 for Drupal allows remote attackers to hijack the authentication of unspecified users for Ajax requests that manipulate files.

SQL injection vulnerability in the Views module before 6.x-2.13 for Drupal allows remote attackers to execute arbitrary SQL commands via vectors related to "filters/arguments on certain types of views with specific configurations of arguments."

Multiple cross-site scripting (XSS) vulnerabilities in revisioning_theme.inc in the Taxonomy module in the Revisioning module 6.x-3.13 and other versions before 6.x-3.14 for Drupal allow remote authenticated users with certain privileges to inject arbitrary web script or HTML via the (1) tags or (2) term parameters.

Cross-site request forgery (CSRF) vulnerability in the clickthrough tracking functionality in the Forward module 6.x-1.x before 6.x-1.21 and 7.x-1.x before 7.x-1.3 for Drupal allows remote attackers to hijack the authentication of administrators for requests that increase node rankings via the tracking code, possibly related to improper "flood control."

The Forward module 6.x-1.x before 6.x-1.21 and 7.x-1.x before 7.x-1.3 for Drupal does not properly enforce permissions for (1) Recent forwards, (2) Most forwarded, or (3) Dynamic blocks, which allows remote attackers to obtain node titles via unspecified vectors.

Cross-site scripting (XSS) vulnerability in display_renderers/panels_renderer_editor.class.php in the admin view in the Panels module 6.x-2.x before 6.x-3.10 and 7.x-3.x before 7.x-3.0 for Drupal allows remote authenticated users with certain privileges to inject arbitrary web script or HTML via the Region title.

Cross-site scripting (XSS) vulnerability in the Meta tags quick module 7.x-2.x before 7.x-2.3 for Drupal allows remote authenticated users with certain permissions to inject arbitrary web script or HTML via unspecified vectors, probably related to "names of entity bundles."
