On August 12, 2025, Microsoft released several security updates for various versions of Microsoft Office. These updates closed critical vulnerabilities across different modules such as Excel, Word, PowerPoint, and OneNote. The updates address Remote Code Execution (RCE) vulnerabilities that could be exploited by attackers to gain control over systems remotely. For users who manually manage their Office installations via MSI packages, these updates are available directly through Microsoft’s support channels. However, for those using the Click-to-Run (C2R) deployment model, the updates are automatically downloaded and installed as part of regular maintenance routines.
For Office 2016, specific security updates were released to address multiple RCE vulnerabilities across Excel, Word, PowerPoint, and OneNote. Each update targets a different set of Common Vulnerabilities and Exposures (CVEs) that have been identified through comprehensive testing by Microsoft’s security teams and external partners like Talos Intelligence.
In addition to the Office suite updates, Microsoft also released several patches for SharePoint Server editions, catering to both subscription-based and on-premises deployments. These updates include fixes for critical vulnerabilities affecting SharePoint Server 2016, 2019, and Subscription Editions.
For more detailed information about these updates, including direct download links and installation instructions, please refer to the official Microsoft documentation available at [https://docs.microsoft.com/en-us/officeupdates/office-updates-msi]. Details on specific CVEs addressed can be found in the linked Knowledge Base (KB) articles. The provided patches are essential not only for maintaining security but also ensuring compliance with organizational standards and regulatory requirements.
Moreover, users of Office Online Server should ensure they update to the latest KB5002752 patch, which includes important fixes for vulnerabilities that could be exploited through web-based attacks.
