  - CVE-2021-44856: A title blocked by AbuseFilter can be created via Special:ChangeContentModel
  due to the mishandling of the EditFilterMergedContent hook return value

  - CVE-2021-44857: It is possible to replace the content of any arbitrary page (that the user
  doesn't have edit rights for)

  - CVE-2021-44858: The 'undo' feature allows an attacker to view the contents of arbitrary
  revisions, regardless of whether they had permissions to do so

  - CVE-2021-45038: The 'rollback' feature could be passed a specially crafted parameter that
  allows an attacker to view the contents of arbitrary pages, regardless of whether they had
  permissions to do so

  - CVE-2021-46146: The WikibaseMediaInfo component is vulnerable to XSS via the caption fields for
  a given media file

  - CVE-2021-46147: MassEditRegex allows CSRF

  - CVE-2021-46148: Some unprivileged users can view confidential information (e.g., IP addresses
  and User-Agent headers for election traffic) on a testwiki SecurePoll instance

  - CVE-2021-46149: A denial of service (resource consumption) can be accomplished by searching for
  a very long key in a Language Name Search

  - CVE-2021-46150: Special:CheckUserLog allows CheckUser XSS because of date mishandling, as
  demonstrated by an XSS payload in MediaWiki:October");
