Stored script execution via unsanitized blog titles

Published May 1, 2023 · Updated Jan 30, 2025

Stored cross-site scripting in ZHENFENG13 MyBlog allows remote authenticated users to execute script in a viewer's browser via a blog title. The blog-management title column renders saved title input without applying MyBlogUtils.cleanString, leaving injected HTML or script unneutralized. Blog-management access is required to store the payload, and execution requires another user to view the affected management or article page.
