Are you managing or owning a website built on Microsoft .NET? 

Then keeping up with Microsoft's security updates is just as important as keeping your website content and functionality up to date. 

Microsoft recently published CVE-2026-47304, a high-severity security vulnerability affecting System.Security.Cryptography.Xml in certain versions of .NET 8, .NET 9 and .NET 10. With a CVSS score of 8.1 (High), the vulnerability could allow an attacker, under applicable conditions, to bypass XML encryption protections and access encrypted data. 

Microsoft has released patched versions to address the vulnerability. And this is where having an actively maintained CMS platform matters.

If your website is powered by eBuilderCMS, we are already on it. eBuilderCMS build 3004.4.59 incorporates the required security update to address CVE-2026-47304. As Microsoft .NET continues to evolve, we continuously review relevant platform and security updates and incorporate the required changes into eBuilderCMS.

Recently, we introduced automatic XML sitemap support. We know XML sitemaps are primarily meant for search engines. But some of our customers asked us whether they could also look better when opened by a person in a browser.

We listened.

With eBuilderCMS build no. 3004.4.59, the XML sitemap now gets a cleaner, human-readable browser view while continuing to remain standards-compliant for search engines.

One release. An important security update, and another improvement driven by our customers.

Stay current. Stay protected. Stay with eBuilderCMS.
