Risk Level: SAFEINDIRECT_PROMPT_INJECTIONDYNAMIC_EXECUTION
Full Analysis
- [INDIRECT_PROMPT_INJECTION]: The skill implements a pattern that processes markdown files from an external source and renders them in the UI, creating an attack surface for indirect injection if the storage is compromised.
- Ingestion points: The
BlogStorageService.csclass in the API project retrieves markdown file content from an Azure File Share. - Boundary markers: The system uses triple-dash
---delimiters to distinguish between YAML metadata and the markdown body content. - Capability inventory: The skill has the capability to render raw HTML to the user's browser via the Blazor
MarkupStringtype. - Sanitization: While it uses the
Markdiglibrary for processing, there is no evidence of an explicit HTML sanitization step (e.g., using a library like HtmlSanitizer) before the content is rendered in thePost.razorcomponent. - [DYNAMIC_EXECUTION]: The skill generates and injects HTML content into the application DOM at runtime.
- Evidence: In
frontend-components.md, thePost.razorcomponent usesrenderedContent = Markdown.ToHtml(post.Content, pipeline);followed by@((MarkupString)renderedContent). This bypasses Blazor's default HTML encoding to render the markdown output, which is a form of dynamic content generation that requires strict input validation.
