Hi, I've discovered a stored Cross-Site Scripting (XSS) vulnerability in the projects/react_blog:
Vulnerability Details:
Version Affected: All versions
Severity: [High/Critical – Stored XSS can have a significant impact. Adjust based on your assessment]
Description: The vulnerability allows malicious attacks to inject scripts through a direct network request. Once embedded, any user's browser viewing the article will execute the malicious script
Steps to Reproduce:
Send a direct POST request (bypassing the user interface) to /addArticle with payload content containing the malicious script.
After the article is successfully created or edited, any user's browser that views the article will run the malicious script.
Suggested Fix or Mitigation:
Server-side: When creating the article, it's essential to sanitize the user's input (content) before processing it to ensure malicious scripts are neutralized.
Client-side: Before displaying the article's content using dangerouslySetInnerHtml, ensure that the description is sanitized using libraries like DOMPurify to prevent script execution.
I've already fixed and tested this issue, and have submitted a pull request with the necessary changes. Please review and merge my pull request at your earliest convenience to resolve this vulnerability. Thanks!
