CVE-2026-24784Network attack vectorHinoki check available

Stored XSS via unneutralized module headers and footers

Published Jan 27, 2026 · Updated Jan 27, 2026

Stored XSS in affected DNN Platform releases allows remote authenticated users to run scripts in other users' browsers via module headers and footers. DNN stores module header and footer values and renders them into page output without neutralizing executable markup; affected branches start at 9.0.0 and 10.0.0. A content-editor role is required, and viewing the affected module triggers execution that exposes browser-accessible data.
