A critical remote code execution (RCE) flaw has been identified in Microsoft Paint, and a fix has been released. However, the fix will only be available through a Microsoft Store update, rather than the usual Windows Update mechanism, leaving users to wonder when and how they will receive the update. This article delves into the details of this flaw and the process of applying the fix, providing users with a better understanding of the potential risks and the steps they can take to protect themselves.

Microsoft Paint, a seemingly innocuous application, has found itself at the center of a high-stakes cybersecurity drama. The latest development in this saga is the release of a fix for a remote code execution (RCE) flaw, identified as CVE-2026-83844, which poses a significant threat to the security of Windows systems. However, this patch has been met with an unexpected twist: the fix will only be available through a Microsoft Store update, rather than the usual Windows Update mechanism.
The RCE flaw, which affects Microsoft Paint, is a serious vulnerability that can be exploited by an attacker to run malicious code on a network-affected service. The severity of this flaw was assessed by Microsoft as important, with a CVSS score of 8.1, indicating a high degree of potential impact. In order for an attacker to successfully exploit this flaw, they would need to possess a deep understanding of the target system.
The origins of this flaw are somewhat murky, with its initial publication on October 13, 2026, accompanied by a security advisory that provided limited information about the vulnerability. It was not until later, when a device-management software maker, Brian Vitko of RFF, conducted a test, that the true extent of the flaw became clear. His test revealed that the newest Paint build available in six countries was 11.2605.81.0, a build that lacked the fix. However, after upgrading his virtual machine to the fixed build, 11.2609.401.0, through the Microsoft Store, he found that the fix had been applied to his machine.
This raises an interesting question: how quickly will other PCs receive this fix? The answer, as of now, is unclear. The security advisory lists no workaround or mitigation for this flaw, and it is up to the user to manually update their copy of Paint through the Microsoft Store or let the Store auto-update install the fixed build.
In order to check every copy of Paint, users can utilize two commands in a PowerShell window opened as administrator. The first command, Get-AppxPackage -AllUsers -Name Microsoft.Paint | Select-Object Version, @{ n = 'Users'; e = { $_.PackageUserInformation.UserSecurityId.Username -join ', ' } }, lists every user's copy of Paint, while the second command, Get-AppxProvisionedPackage -Online | Where-Object DisplayName -eq 'Microsoft.Paint' | Select-Object Version, will list the provisioned copy of Paint.
It is worth noting that this fix is the newest Paint build available in all ten countries, as checked by The Hacker News. The fixed build, 11.2609.401.0, is the newest Paint build in all ten countries The Hacker News checked today.
The advisory lists no workaround or mitigation for this flaw, and it is up to the user to manually update their copy of Paint through the Microsoft Store or let the Store auto-update install the fixed build. However, it is recommended that users run both commands again and check that every copy shows 11.2609.401.0 or later.
An attacker could exploit the flaw by sending "a specially crafted packet to an affected service over the network," the advisory says, but it does not name the service. The attack would require no sign-in and no user assistance. The flaw was not in the Known Exploited Vulnerabilities catalog run by the U.S. Cybersecurity and Infrastructure Security Agency when The Hacker News checked today.
In conclusion, the recent release of a fix for the Microsoft Paint RCE flaw is a timely reminder of the importance of keeping our software up-to-date. While the process of applying this fix may seem straightforward, the fact that it will only be available through a Microsoft Store update rather than the usual Windows Update mechanism adds a layer of complexity to this already serious issue.
