CVE-2025-52486Network attack vector

Reflected script execution via unencoded TokenReplace output

Published Jun 21, 2025 · Updated Jun 23, 2025

Reflected XSS in DNN Platform 6.0.0 through 10.0.0 allows remote attackers to execute script in a user's browser via a crafted URL. BaseCustomTokenReplace exposed property-source results without default HTML encoding, allowing affected SkinObjects to place URL-derived token values into HTML unchanged. Exploitation requires a user to open the crafted URL; injected script runs in the site's origin and can read browser-accessible data.
