CVE-2026-24837: DotNetNuke.Core Vulnerable to Stored XSS in Module Deletion Confirmation Modal

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Starting in version 9.0.0 and prior to versions 9.13.10 and 10.2.0, a module friendly name could include scripts that will run during some module operations in the Persona Bar. Versions 9.13.10 and 10.2.0 contain a fix for the issue.

Security readout for executives and security teams

Plain-English summary

CVE-2026-24837 is a stored cross-site scripting flaw in DNN Platform. A malicious script placed in a module friendly name can execute during some Persona Bar module operations, including deletion confirmation workflows. It affects DNN 9.0.0 through versions before 9.13.10 and 10.0.0 through versions before 10.2.0. Fixed versions are available.

Executive priority

Prioritize remediation for externally exposed DNN admin environments and sites with many privileged users. A patch exists, and the issue can affect confidentiality, integrity, and availability in the vendor’s CVSS assessment, but exploitation requires privileged access and user interaction.

Technical view

The issue is CWE-79 stored XSS in Dnn.Platform. The CVSS 3.1 score is 7.7, with high privileges required, user interaction required, network attack vector, and changed scope. The vulnerable data is the module friendly name, which can be rendered unsafely during Persona Bar module operations. Versions 9.13.10 and 10.2.0 contain the fix.

Likely exposure

Exposure is limited to DNN sites running affected versions where a high-privileged user or compromised privileged account can modify module friendly names. Risk is higher for internet-facing administrative portals and environments with multiple content administrators.

Exploitation context

The source bundle does not indicate active exploitation, and this CVE is not listed as KEV. Exploitation requires high privileges and a user interaction path, but successful stored XSS could affect administrative users viewing affected Persona Bar workflows.

Researcher notes

Evidence is limited to the CVE record and GitHub security advisory. The advisory confirms fixed versions but no public exploitation status in the provided sources. Avoid assuming affected forks, plugins, or unsupported releases beyond the stated Dnn.Platform version ranges.

Mitigation direction

  • Upgrade DNN Platform to 9.13.10, 10.2.0, or later fixed releases.
  • Review vendor advisory GHSA-vm5q-8qww-h238 for deployment-specific guidance.
  • Restrict administrative access to trusted users until upgraded.
  • Audit module friendly names for unexpected script-like content.

Validation and detection

  • Inventory DNN Platform versions across all sites.
  • Flag versions >=9.0.0 and <9.13.10 as affected.
  • Flag versions >=10.0.0 and <10.2.0 as affected.
  • Confirm upgraded systems report version 9.13.10, 10.2.0, or later.
  • Review administrative change logs for suspicious module name changes.
