CVE-2022-0159Network attack vector

Stored script execution via unencoded display names

Published Jan 12, 2022 · Updated Aug 2, 2024

Stored cross-site scripting in Orchard Core before 1.2.1 allows remote authenticated users to run script in another user's browser. Content-type display names pass through IHtmlLocalizer and Html.Raw in administrative create, edit, list, and dashboard views, emitting stored markup without encoding. Dashboard access and content-management permission are required, and execution occurs when another user opens an affected view, exposing that user's site privileges and accessible data to the injected script.
