Security readout for executives and security teams
Plain-English summary
CVE-2026-24784 is a cross-site scripting issue in DNN/DotNetNuke. A user with content editor privileges could place script content in module headers or footers, causing it to run for other users. This is not described as unauthenticated compromise, but it can expose sensitive user data in affected sites.
Executive priority
Treat as a near-term remediation item for public or business-critical DNN sites. Prioritize upgrades where many users can edit content or where authenticated users handle sensitive information. There is no provided evidence of active exploitation.
Technical view
DNN.Platform versions 9.0.0 through before 9.13.10, and 10.0.0 through before 10.2.0, are affected by CWE-79 XSS in module header/footer handling. CVSS 3.1 is 6.8 with network access, low complexity, high privileges required, no user interaction, changed scope, and high confidentiality impact.
Likely exposure
Exposure is limited to DNN sites running affected versions where users have content editor permissions. The issue matters most on sites with many editors, delegated content administration, or sensitive authenticated user sessions.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires an account with content editor capability, but successful abuse could run script in other users’ browsers.
Researcher notes
The advisory describes a privilege-dependent XSS condition in module headers and footers. Evidence provided is limited to the CVE data and GitHub advisory. Do not assume broader DNN components, other versions, or active exploitation without additional vendor or threat intelligence confirmation.
Mitigation direction
- Upgrade DNN.Platform to 9.13.10 or 10.2.0, as applicable.
- Review the GitHub advisory for any vendor-specific deployment notes.
- Limit content editor permissions to trusted users only.
- Review module headers and footers for unexpected script content.
Validation and detection
- Inventory all DNN/DotNetNuke instances and record installed versions.
- Confirm affected 9.x instances are at least 9.13.10.
- Confirm affected 10.x instances are at least 10.2.0.
- Review accounts with content editor privileges.
- Inspect module header and footer content for unauthorized changes.
