Descrição técnica

Waline is a comment system with backend support. In versions 3.15.2 and prior, the @waline/client UserList widget builds its DOM by concatenating server-returned commenter fields directly into root.innerHTML with no HTML escaping. The commenter nick and link are stored and returned verbatim by the server (only the comment body is sanitized), and the link field is never sent to the spam filter. So an unauthenticated visitor who posts a comment with link = x"><img src=x onerror=...> achieves stored cross-site scripting that executes, with no interaction, in the browser of every visitor to a page that embeds the UserList widget. At time of publication, there are no publicly available patches.

———AsiaInfo BSS Platform 9.2 before 9.2.38 has a stored cross-site scripting (XSS) vulnerability in the menu icon upload function. An authenticated user with ordinary application privileges can upload an SVG file containing embedded JavaScript, which is served from the application origin. Normal menu rendering uses an HTML <img> element and does not execute the SVG script; exploitation requires a victim to load the uploaded SVG as a document (by directly navigating to its URL, or via <object>/<iframe>), in which case the script executes under the application origin.6h
