Background
DotNetNuke.Core is a widely used framework for building web applications on the .NET platform. It provides essential features for content management, user authentication, and extensibility through modules. However, it has been identified that the codebase raises several security-related code analysis warnings, which could potentially expose applications to vulnerabilities if not addressed.
Vulnerability Detail
The vulnerability arises from multiple code analysis warnings triggered within the DotNetNuke.Core package, specifically warnings CA3075, CA5366, CA5371, CA5368, CA5369, CA5372, CA5379, CA5350, and CA5351. These warnings primarily concern the handling of XML documents, particularly the disabling of Document Type Definition (DTD) processing, which is crucial for preventing XML External Entity (XXE) attacks. Additionally, there are concerns regarding the selection of cryptographic algorithms, which could lead to weak security implementations if outdated or insecure algorithms are used.
How To Fix
Latest published version: 10.4.0 as of 23 Oct 2026
Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.
If you need the minimum change
10.2.2
This is the first release that contains the fix.

Workaround
As a temporary workaround, developers can manually review the code to ensure that DTD processing is disabled in XML handling and that secure cryptographic algorithms are being used. This may involve configuring XML parsers to prevent DTD processing and auditing cryptographic implementations to ensure they comply with current security standards.
Conclusion
In summary, the DotNetNuke.Core package has raised several security code analysis warnings that need to be addressed to maintain the security of applications built on this framework. Updating to the latest version and implementing recommended security practices will help mitigate potential risks.
