The Paragraphs module allows Drupal Site Builders to make content organization cleaner so that you can give more editing power to end-users.

The module doesn't sufficiently check access to create new paragraph entities which can cause access bypass issues when used in combination with other contributed modules.

Solution: 

Install the latest version:

• If you use the Paragraphs module for Drupal 8.x, upgrade to Paragraphs 8.x-1.5

The session limit module enables a site administrator to set a policy around the number of active sessions users of the site may have. This is typically set to one so that you can only be logged in once with the same user account.

In one configuration of the module, when a user logs in with another session elsewhere already active, the module asks the user which session should be closed before they can proceed with login. The module does not sufficiently tokenise the list of sessions so that the user's session keys can be found through inspection of the form.

This vulnerability is mitigated by the fact that an attacker must already be able to intercept the contents of the HTML page to exploit the issue. That ability to intercept may come from Cross Site Scripting. This makes a Cross Site Scripting vulnerability worse than it would normally be.

Solution: 

Install the latest version:

• If you use the Session Limit module for Drupal 7.x, upgrade to 7.x-2.3
• If you use the Session Limit module for Drupal 8.x, upgrade to 8.x-1.0-beta3

This module enables you to resolve the provided Drupal path in order to find the canonical path and information about the resolved entity. This information includes entity type ID, entity ID, entity UUID and entity label.

Description

Content moderation - Moderately critical - Access bypass - Drupal 8

In some conditions, content moderation fails to check a users access to use certain transitions, leading to an access bypass.

In order to fix this issue, the following changes have been made to content moderation which may have implications for backwards compatibility:

ModerationStateConstraintValidator

Two additional services have been injected into this service. Anyone subclassing this service must ensure these additional dependencies are passed to the constructor, if the constructor has been overridden.

StateTransitionValidationInterface

An additional method has been added to this interface. Implementations of this interface which do not extend the StateTransitionValidation should implement this method.

Implementations which do extend from the StateTransitionValidation should ensure any behavioural changes they have made are also reflected in this new method.

User permissions

Previously users who didn't have access to use any content moderation transitions were granted implicit access to update content provided the state of the content did not change. Now access to an associated transition will be validated for all users in scenarios where the state of content does not change between revisions.

External URL injection through URL aliases - Moderately Critical - Open Redirect - Drupal 7 and Drupal 8

The path module allows users with the 'administer paths' to create pretty URLs for content.

In certain circumstances the user can enter a particular path that triggers an open redirect to a malicious url.

The issue is mitigated by the fact that the user needs the administer paths permission to exploit.

Anonymous Open Redirect - Moderately Critical - Open Redirect - Drupal 8

Drupal core and contributed modules frequently use a "destination" query string parameter in URLs to redirect users to a new destination after completing an action on the current page. Under certain circumstances, malicious users can use this parameter to construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks.

This vulnerability has been publicly documented.

RedirectResponseSubscriber event handler removal

As part of the fix, \Drupal\Core\EventSubscriber\RedirectResponseSubscriber::sanitizeDestination has been removed, although this is a public function, it is not considered an API as per our API policy for event subscribers.
If you have extended that class or are calling that method, you should review your implementation in line with the changes in the patch. The existing function has been removed to prevent a false sense of security.

Solution

Upgrade to the most recent version of Drupal 7 or 8 core.

• If you are running 7.x, upgrade to Drupal 7.60.
• If you are running 8.6.x, upgrade to Drupal 8.6.2.
• If you are running 8.5.x or earlier, upgrade to Drupal 8.5.8.

Minor versions of Drupal 8 prior to 8.5.x are not supported and do not receive security coverage, so sites running older versions should update to the above 8.5.x release immediately. 8.5.x will receive security coverage until May 2019.

This module provides printer-friendly versions of content, including send by e-mail and PDF versions.

The module doesn't sufficiently sanitize the arguments passed to the wkhtmltopdf executable, allowing a remote attacker to execute arbitrary shell commands. It also doesn't sufficiently sanitize the HTML content passed to dompdf, allowing a privileged attacker to execute arbitrary PHP code.

This vulnerability is mitigated by the fact that the site must have either the wkhtmltopdf or dompdf sub-modules enabled and selected as the PDF generation tool. In the case of the dompdf vulnerability, the attacker must be able to write content to the site.

Solution: 

Install the latest version:

• If you use the print module for Drupal 7.x, upgrade to print 7.x-2.1

In alternative, disable PDF generation, or replace the PDF generation library with another of the supported versions.

Project: RenderkitDate: 2018-September-19Security risk: Moderately critical 11∕25 AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:UncommonVulnerability: Access bypassDescription: 

This module, typically in combination with cfr:cfrplugin, allows to compose behaviors from granular components. One of such behaviors is to display a list of related entities, for a given source entity and a given entity relation (e.g. an entity reference field).

The components that display related content do not check if the user has access to view the related entities. This way e.g. unpublished nodes may be displayed to anonymous visitors.

This vulnerability is mitigated by the facts that
- a site builder must have used the component that displays "related" entities for a source entity, using cfr:cfrplugin, OR a programmer has used one of the affected components in code.
- a source entity displayed this way must reference access-restricted content.
