Security readout for executives and security teams
Plain-English summary
DNN Platform has a stored cross-site scripting issue in module descriptions. A module installed with rich text in its description could include script content that runs when a user views it in the Persona Bar. This affects versions before 9.13.10 and 10.0.0 through before 10.2.0.
Executive priority
Prioritize patching for public-facing or business-critical DNN sites, especially where multiple administrators or third-party modules are used. The issue requires elevated access, but successful exploitation could affect sensitive administrative sessions.
Technical view
CVE-2026-24833 is CWE-79 stored XSS in Dnn.Platform. The CVSS 3.1 score is 7.7 with high privileges and user interaction required, but scope is changed and confidentiality, integrity, and availability impacts are rated high. Fixed versions are 9.13.10 and 10.2.0.
Likely exposure
Organizations running DNN Platform below 9.13.10, or 10.x versions below 10.2.0, are exposed. Risk is most relevant where users can install modules or manage module metadata and where administrators use the Persona Bar.
Exploitation context
The provided sources do not report active exploitation, and this CVE is not listed as KEV. Exploitation appears to require high privileges and a user viewing affected content in the Persona Bar, which reduces likelihood but not potential impact.
Researcher notes
Evidence is limited to the CVE record and GitHub advisory. No public exploit activity is cited in the provided sources. Focus validation on version exposure, module installation workflows, Persona Bar usage, and administrative permission boundaries.
Mitigation direction
- Upgrade affected DNN Platform 9.x installations to 9.13.10.
- Upgrade affected DNN Platform 10.x installations to 10.2.0.
- Review the GitHub advisory for any updated vendor guidance.
- Limit module installation privileges to trusted administrators until upgraded.
Validation and detection
- Inventory all DNN Platform instances and record exact versions.
- Confirm whether versions match the affected ranges.
- Verify upgraded systems report 9.13.10 or 10.2.0 as appropriate.
- Review installed modules and descriptions for unexpected rich text content.
- Check whether module management permissions are limited to trusted users.
