Browser script execution via unsanitized Excerpt rendering
Published Sep 2, 2022 · Updated Aug 3, 2024
Stored XSS in Miniblog.Core 1.0 allows remote authenticated users to execute scripts in visitors' browsers through the Excerpt field. The /blog/edit workflow accepts event-handler HTML in Excerpt and later renders the saved value on the home page without neutralizing executable markup. Administrative access is required to save the payload, and execution occurs when another user loads the affected home page.
