Hi,

You need to apply the March 2026 MSRC hotfix for SCOM 2019 UR6, which is KB5073251.

The important point is that this hotfix is for the SCOM Web Console component. The security issue is related to the PowerShell widget in SCOM dashboards/web console, so you must install the hotfix on the server or servers where the SCOM Web Console role is installed.

1. Confirm the prerequisite

KB5073251 requires System Center Operations Manager 2019 Update Rollup 6.

Your current build 10.19.10649.0 indicates that you are already on SCOM 2019 UR6, so the prerequisite should already be met.

If another environment is still below UR6, first install SCOM 2019 Update Rollup 6, and only then install this hotfix.

2. Identify the Web Console server

Check where the SCOM Web Console role is installed.

In smaller environments, the Web Console may be installed directly on a Management Server. In larger environments, it may be installed on one or more dedicated web servers, possibly behind a load balancer.

Install the hotfix on every server that hosts the SCOM Web Console role.

3. Download the hotfix

Download KB5073251 from Microsoft Support / Microsoft Update Catalog.

The file you need for SCOM 2019 is:

KB5073251-amd64-WebConsole.msp

4. Install the hotfix

Log on to the Web Console server with an account that has local administrator rights.

Open an elevated Command Prompt and run the MSP file, for example:

msiexec.exe /p KB5073251-amd64-WebConsole.msp /L*v C:\Temp\KB5073251-WebConsole.log

For a silent installation, you can use:

msiexec.exe /p KB5073251-amd64-WebConsole.msp /qn /L*v C:\Temp\KB5073251-WebConsole.log

Make sure that C:\Temp exists before running the command.

5. Restart if required

If the installer requests a restart, reboot the server during a maintenance window.

If no restart is requested, I would still recommend restarting IIS or recycling the affected application pools after the installation, for example:

iisreset

Use a proper maintenance window if this is a production Web Console used by operators.

6. Validate the installation

After the installation, validate the following:

  1. The SCOM Web Console opens successfully.
  2. Existing dashboards still load correctly.
  3. PowerShell-widget based dashboards behave as expected.
  4. Non-admin users can no longer edit PowerShell widgets.
  5. Your vulnerability scanner no longer reports CVE-2026-20967 after a fresh scan.
  6. You can also check the local installation history / installed updates for KB5073251.

7. Common reasons why the update may not install

If the MSP says that the update is not applicable, usually one of these is true:

The server does not have the SCOM Web Console role installed.

The SCOM environment is not yet on SCOM 2019 UR6.

You are running the MSP on a Management Server that does not host the Web Console.

You are using the wrong package for the installed SCOM version.

8. Important clarification

Do not confuse this with an upgrade to SCOM 2022 or SCOM 2025. For SCOM 2019 build 10.19.10649.0, the correct remediation path for this CVE is to apply the SCOM 2019 UR6 MSRC hotfix KB5073251, which brings the affected component to the fixed build level 10.19.10658.0.

Also, if your environment has multiple Web Console servers behind a load balancer, patch all of them. Otherwise, the vulnerability scanner may still detect the vulnerable version on one of the remaining nodes.

Best regards,
Stoyan

    To apply the security patch for CVE-2026-20967 and upgrade System Center Operations Manager (SCOM) 2019 from version 10.19.10649.0 to the fixed version 10.19.10658.0, you will need to apply the March 2026 Update Rollup package. First, download the specific update rollup MSP files from the Microsoft Update Catalog or your volume licensing portal. Before running the installation, open the Operations Manager Shell and take your management servers out of production by placing your monitored gateways and agents into maintenance mode.

    Next, open an elevated Command Prompt with administrative privileges, navigate to the directory where you extracted the patch files, and execute the server update file (KBxxxxxxx-AMD64-Server.msp) to patch the core server files in your installation directory. Once the binaries are successfully updated, you must run the accompanying SQL script files against your OperationsManager and OperationsManagerDW databases to update the database schema to match the new build version. After updating the databases, restart the System Center Management configuration services, open the Operations Manager console, and navigate to the Administration pane to approve the pending updates for your deployed agents so they pull the matching 10.19.10658.0 binaries.
