CVE-2025-59548Network attack vector

Reflected XSS via crafted FileBrowser URLs

Published Sep 23, 2025 · Updated Sep 23, 2025

Reflected XSS in DNN Platform before 10.1.0 allows remote attackers to execute JavaScript in a user's browser via a crafted FileBrowser URL. The advisory identifies FileBrowser URL handling but does not disclose the parameter or code path that fails to neutralize injected JavaScript. Exploitation requires a user to click the link, and the upstream advisory reports greater consequences when the victim has elevated DNN permissions.
