Wysiwyg - Moderately critical - Cross site scripting - SA-CONTRIB-2022-003
This module enables you to integrate various What-You-See-Is-What-You-Get (WYSIWYG) rich text editors into Drupal fields with text formats allowing markup for easier editing.
The module doesn't sufficiently sanitize user input before attaching a WYSIWYG editor to an input field such as a textarea. If the editor used has an XSS vulnerability this would allow for example a commenter to put specially crafted markup which could trigger the vulnerability when viewed in the editor by an administrator.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission to create content using a text format with an attached and XSS vulnerable rich text editor.
Solution:Install the latest version:
- If you use the Wysiwyg module for Drupal 7.x, upgrade to WYSIWYG 7.x-2.9
After upgrading verify that text formats which have a WYSIWYG editor profile also uses a text filter, such as Core's "Limit allowed HTML tags", if accessible by untrusted users.
A list of known compatible input filters that will be applied is shown when configuring a WYSIWYG editor profile along with a status indicator.
It is recommended to always be using the latest stable version of any installed editor libraries.

Simple OAuth (OAuth2) & OpenID Connect - Moderately critical - Access bypass - SA-CONTRIB-2022-002
This module enables you to implement OAuth 2.0 authentication for Drupal.
The module doesn't sufficiently verify client secret keys for "confidential" OAuth 2.0 clients when using certain grant types. The token refresh and client credentials grants are not affected.
This vulnerability is mitigated by the fact that the vast majority of OAuth 2.0 clients in the wild are public, not confidential. Furthermore, all affected grant types still require users to authenticate to Drupal during the OAuth flow.
The implicit grant type is insecure for other reasons (and still requires user authentication) and is disabled by default.
Sites at risk of information disclosure would be specifically configured to restrict access based on the OAuth client's confidentiality status and configured scopes, not only traditional Drupal user permissions and roles.
Further mitigation includes configuring allowed redirect URIs for clients. This is an OAuth best practice for guarding against man-in-the-middle attacks on authorization codes, and prevents redirection to imposter clients.
Anyone implementing OAuth 2.0 on their Drupal site is also encouraged to review the relevant RFCs and Internet-Drafts pertaining to OAuth security.
Solution:Install the latest version:
- If you use the simple_oauth module for Drupal 9.x, upgrade to simple_oauth-8.x-4.6, 5.0.6 or 5.2.0.
Important note: 8.x-4.6 will be the last release for the 8.x-4.x branch. Support for this major version will end February 28, 2022. The upgrade path to 5.x is easy, supported and well-tested. All users of versions < 5 should upgrade to 5.2.0.
The 5.0.x version will be supported until July 31, 2022. Read the 5.2.0 change record for information about changes to previously non-spec-compliant response codes and messages.

Super Login - Critical - Access bypass - SA-CONTRIB-2022-001
This module enables you to login with an email address.
The module doesn't sufficiently check if a user account is active when using email login.
This vulnerability is mitigated by the fact that an attacker must have an account in the website that is blocked.
Solution:Install the latest version:
- If you use the Super Login module for Drupal 8.x, upgrade to Super Login 8.x-1.7
- Greg Knaddison of the Drupal Security Team
Mail Login - Moderately critical - Access bypass - SA-CONTRIB-2021-047
This modules enables users to login via email address.
This module does not sufficiently check user status when authenticating.
Solution:Install the latest version:
- If you use the mail_login module for Drupal 8 or 9, upgrade to Mail Login 8.x-2.5

Search API Pages - Critical - Cross Site Scripting - SA-CONTRIB-2021-046
This module enables you to create simple search pages based on Search API without the use of Views.
The module doesn’t sufficiently escape all variables provided for custom templates.
This vulnerability is mitigated by the fact that the default template provided by the module is not affected.
Solution:Install the latest version:
- If you use the Search API Pages module for Drupal 7.x, upgrade to Search API Pages 7.x-1.6

Webform - Critical - Cross Site Scripting, Access Bypass - SA-CONTRIB-2021-045
This module enables you to build forms and surveys in Drupal.
The module doesn't sufficiently check access for administrative features for webforms attached to nodes using the Webform Node module. This may reveal submitted data or allow an attacker to modify submitted data. Additionally, for sites with webforms that send emails and store submissions this vulnerability would allow an attacker to use the site as an email relay (i.e. sending arbitrary emails).
There is no mitigation for this vulnerability. If you have the Webform Node module enabled you must update the Webform module.
Cross Site Scripting:The Webform module enables site builders to create forms and surveys.
The Webform module doesn't sufficiently filter HTML when an element's 'Help title' and an 'Image Select' element's image text contain specially crafted malicious text.
This vulnerability is mitigated by the fact that an attacker must be able to create or edit webforms.
Solution:Install the latest version:
- If you use the Webform module for Drupal 9.x, upgrade to Webform 6.1.2 or Webform 6.0.6
- If you use the Webform module version 8.x-5.x it is affected by this issue and is unsupported. You should upgrade to Webform 6.

OpenID Connect Microsoft Azure Active Directory client - Moderately critical - Access Bypass - SA-CONTRIB-2021-044
This module enables users to authenticate through their Microsoft Azure AD account.
The module does not sufficiently check authorization before updating user profile information in certain non-default configurations. This could lead a user being able to hijack another existing account.
This vulnerability is mitigated by the fact that an attacker must have knowledge of user accounts that have the administrator role or accounts with the 'Set a password for local authentication' permission. In addition the site must be configured with the 'Update email address in user profile' setting turned on.
Solution:Install the latest version:
- If you use the OpenID Connect Microsoft Azure Active Directory client module 7.x-1.x, upgrade to OpenID Connect Microsoft Azure Active Directory client 7.x-1.2
- If you use the OpenID Connect Microsoft Azure Active Directory client module 8.x-1.x, upgrade to OpenID Connect Microsoft Azure Active Directory client 8.x-1.4

Loft Data Grids - Moderately critical - XML External Entity (XXE) Processing - SA-CONTRIB-2021-043
This module enables aklump/loft_data_grids to be used as a Drupal module.
Excel support was provided by https://packagist.org/packages/phpoffice/phpexcel, which is abandoned and there are known security vulnerabilities: [CVE-2018-19277]: PHPOffice/PhpSpreadsheet#771. Excel support has since been replaced with the newer https://github.com/PHPOffice/PhpSpreadsheet library.
This module provides an API and This vulnerability is not exploitable in the module itself. This vulnerability only exists if custom code or another module uses the API of this module to read a spreadsheet.
Solution:Upgraded to the the latest version.
- https://www.drupal.org/project/loft_data_grids/releases/7.x-2.4
- https://www.drupal.org/project/loft_data_grids/releases/8.x-1.4

Linkit - Moderately critical - Cross Site Scripting - SA-CONTRIB-2021-042
Linkit provides an easy interface for internal and external linking with WYSIWYG editors by using an autocomplete field.
It does not sufficiently sanitize user input.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission to create or edit an entity bundle.
Solution:Install the latest version:
- If you use the Linkit module for Drupal 8.x, upgrade to Linkit 8.x-4.4
