How the CVE Works:
This Cross-Site Scripting (XSS) vulnerability exists within the DotNetNuke (DNN) platform’s module management. The affected `DotNetNuke.Core` component improperly handles rich text input for module s. An attacker with permissions to edit a module’s can inject malicious JavaScript code within the field, leveraging the rich text support. This user-controlled input is not sufficiently sanitized or encoded before being persisted to the database. When the module is later rendered on a page, the stored script is executed in the browser of any user viewing that page, within the security context of the vulnerable DNN site, leading to client-side code execution.
dailycve form:
Platform: DotNetNuke (DNN)
Version: <9.13.10, 10.0.0-10.1.x
Vulnerability : Stored XSS
Severity: Critical
date: 2026-01-28
Prediction: Patched (9.13.10/10.2.0)
What Undercode Say:
Analytics:
grep -r "Module" /path/to/dnn/Platform/
cat /Database/Scripts/Module_Schema.sql
curl -X POST "http://target/page" --data "=<script>alert('XSS')</script>"
How Exploit:
1. Attacker authenticates to DNN.
2. Edits any available module .
3. Inserts JavaScript payload into field (e.g., ``).
4. Saves the module.
5. Victim views the page containing the module.
6. Injected script executes in victim’s browser.
Protection from this CVE:
Update to DNN Platform version 9.13.10 or 10.2.0. Implement strict output encoding for all user-controlled data rendered in HTML contexts. Apply a Content Security Policy (CSP).
Impact:
Session hijacking. Data theft. Unauthorized actions.
