After installation, remember to run the SharePoint 2019 configuration wizard (SharePoint 2019 Products Configuration Wizard), or the following command:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important

Always install both packages in this order:

1. language independent (updates language-independent components)
2. language dependent (updates language-dependent components)

For language-dependent packages (language dependent), it does not matter which language you select, because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2019 farm, you must subsequently reinstall the language-dependent package (language dependent).

Remember that, in addition to SharePoint, the Distributed Cache service must also be updated; see How to update Distributed Cache correctly and, for Office Online Server, you must have the current RTM version; see  How to update Office Online Server.

Included fixes and improvements

The list of fixes and improvements in this CU consists of excerpts from official Microsoft KB articles in their original language (EN).

SharePoint Server 2019

This security update resolves a cross-site-scripting (XSS) vulnerability that exists if Microsoft SharePoint Server does not correctly sanitize a specially crafted web request to an affected SharePoint server. To learn more about the vulnerability, see the following security advisories:

• Microsoft Common Vulnerabilities and Exposures CVE-2020-0891
• Microsoft Common Vulnerabilities and Exposures CVE-2020-0892
• Microsoft Common Vulnerabilities and Exposures CVE-2020-0893
• Microsoft Common Vulnerabilities and Exposures CVE-2020-0894
• Microsoft Common Vulnerabilities and Exposures CVE-2020-0850
• Microsoft Common Vulnerabilities and Exposures CVE-2020-0852

This security update contains improvements and fixes for the following nonsecurity issues in SharePoint Server 2019:

• Users navigate to a document library and open a Links list in Job Access With Speech (JAWS) by using a keyboard shortcut (Alt+F7) to see all links on the page. Every document in the library contains the Open Menu link to open the Edit Control Block (ECB) menu. Therefore, it is not possible to know which document belongs to which link. This update fixes the issue.

  Note To fix this issue, you have to install update 4484277 together with this update.

• Fixes an issue that prevents users from switching content type when they create items in a list.
• Removes the Link command from the New menu in custom lists when content types are enabled.

Note To fix these issues, you have to install update 4484277 together with this update.

• When you have a hyperlink column as the first column in your view, and you have a very long navigation list, the edit box for the hyperlink column in Quick Edit opens underneath the navigation pane. This makes it difficult to edit or add a value in the edit box.
• Fixes an issue in which creating a site master fails if multiple authentication methods are used for the web application.
• When you use the Edge browser, CSPReporting.aspx is requested multiple times during page loading when you access modern pages. This update fixes this issue.
• Screen readers such as Narrator don’t show an “alt” text entry for icons of Search buttons when you bulk edit multiple resources.
• After you import an updated thesaurus into the Search Service Application, you may see a “something went wrong” error message when you search from the “Search Box”.
• When you use the Finnish locale version, the dates for Blog and List items don’t render correctly. This update fixes this issue.
• When you copy items that are declared as records through Windows Explorer, the copied items keep the record declaration status. This update fixes this issue.
• Fixes an issue that causes content deployment jobs to fail if a document library contains a file that has multiple versions.

This security update contains fixes for the following nonsecurity issues in Project Server 2019:

• After you edit a project in Project Web App, it may take a long time to save the project. This is especially true if there are many custom field values. This causes slower publishing, check-in jobs, and other related actions.
• Editing a project in Project Web App or approving status updates uses the Project Calculation Service (PCS). In some situations, PCS crashes while it closes the given project. The crash detail is logged in the Unified Logging System (ULS) logs, and it resembles the following:

  “The worker encountered a very serious error and will shut down. Exception code was: 0xc0000005 (EXCEPTION_ACCESS_VIOLATION).”

• Consider the following scenario:
  • You have an enterprise resource custom field.
  • You edit a resource and assign a value to the field.
  • You delete the enterprise resource field.
  • You edit the resource, and save your changes.

In this scenario, the process fails, and you receive the following error message:

“Unknown error has occurred”
