Stored XSS via unsanitized article content
Published May 1, 2023 · Updated Jan 30, 2025
Stored XSS in ZHENFENG13 MyBlog allows remote authenticated users to inject script through the blog article editing page. The article-editing flow stores untrusted article content without applying MyBlogUtils.cleanString, and the saved content is rendered on an article page. Low-privilege editing access is required, and the payload runs only when another user views the affected content, enabling browser-context data access or content changes.
