Submit #782265: 1Panel-dev MaxKB <= v2.6.1 Stored XSSinfo

Title1Panel-dev MaxKB <= v2.6.1 Stored XSS
DescriptionA Stored Cross-Site Scripting (XSS) vulnerability exists in MaxKB. Authenticated users with dataset management permissions can create paragraphs containing arbitrary HTML/Markdown content. The application stores this content without sanitization and subsequently renders it in the UI using the md-editor-v3 MdPreview component, which does not sanitize HTML by default. This allows attackers to inject malicious JavaScript that executes when other users, including administrators, view the paragraph or execution details.
