Alert meAnalysisAIv1 – Mar 12, 2026
DotNetNuke versions prior to 9.13.10 and 10.2.0 allow arbitrary script execution in the Persona Bar administrative interface through unsanitized richtext content in module descriptions. An authenticated attacker with module installation privileges can inject malicious scripts that execute in the context of administrative users, potentially compromising sensitive data or administrative functions. This vulnerability requires high privileges and user interaction to exploit, with no public patch currently available for affected versions.
Earlier versions of this analysis (1)
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to versions 9.13.10 and 10.2.0, a module could install with richtext in its description field which could contain scripts that will run for user in the Persona Bar. [CVSS 7.6 HIGH]
RemediationAI
Monitor vendor advisories for a patch. Implement output encoding and Content Security Policy headers. Restrict network access to the affected service where possible.

DescriptionGitHub Advisory
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to versions 9.13.10 and 10.2.0, a module could install with richtext in its description field which could contain scripts that will run for user in the Persona Bar. Versions 9.13.10 and 10.2.0 contain a fix for the issue.
Executive ViewAI
DNN CMS installations are vulnerable to stored cross-site scripting (XSS) attacks through malicious module descriptions that execute in the administrative Persona Bar interface. Attackers with module installation privileges could compromise administrator accounts and gain control of the CMS platform, affecting all content and user data managed by the system.
Restrict module installation capabilities to a limited set of verified administrators; implement Web Application Firewall (WAF) rules to block script execution in module description fields; disable or isolate the Persona Bar for non-essential administrative users; enforce Content Security Policy (CSP) headers to prevent inline script execution; conduct regular audits of installed modules and remove any with suspicious descriptions.
