15.5.2022    |    komentáře   komentářů: 0

A new cumulative update (May 2022 CU) has been released for SharePoint Server 2019.

SP Build:
16.0.10386.20011 (Language independent CU)
16.0.10386.20015 (Language dependent CU)

SharePoint 2019 CU – KB articles describing the CU:

  • KB 5002207 – May 2022 Update for SharePoint Server 2019 (language independent)
  • KB 5002206 – May 2022 Update for SharePoint Server 2019 (language dependent)

SharePoint Server 2019 CU – CU download links:

After installation, remember to run the 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 notes

Always install both packages in this order:

  1. language independent components (core CU)
  2. language-dependent components (language CU)

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

If you install a new language pack on a SharePoint Server 2019 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).

Note for this CU:

Both updates require an existing SharePoint Server 2019 installation; KB 5002207 specifically requires the release version.

Installing KB 5002206 can require a computer restart.

Run the configuration wizard on every server in the farm after applying the updates, including servers without additional language packs, which also need both update packages.

Goßner confirms that cached JavaScript can cause missing navigation or editing controls after this CU. Clear the browser cache or use Ctrl+F5. Side-by-side patching can force the updated scripts to load; update its token with every patch installation.

Included fixes and improvements

The following overview summarizes the fixes and improvements in this CU based on the official Microsoft KB articles.

SharePoint Server 2019

KB 5002207 addresses remote code execution in SharePoint Server, tracked as CVE-2022-29108.

KB 5002207 also corrects these nonsecurity problems:

  • Publishing new forms is possible again on sites based on the CMSPUBLISHING template.

  • Grid view editing now handles deletion of multiple list rows correctly.

  • Document uploads to a library no longer encounter the erroneous 404 not found response when SAML authentication has expired before the upload.

  • Upgrading a content database from SharePoint Server 2013 or 2016 to SharePoint Server 2019 preserves extremely long links embedded in documents.

The following corrections require KB 5002206 and KB 5002207 together:

  • The home page retains the Create Site control when the screen resolution is set below 400%.

  • The New link dialog supplies its missing dialog role and accessible name.

  • Buttons in a communication site’s sharing panel now show their text.

  • Filtering works again for lookup columns containing a DateTime value.

  • The Share with me page works correctly in Internet Explorer.

  • Modern search results display the folder icon correctly.

  • Elements on the new Web Part page now provide the child roles required for accessibility.
