Summary

CVE-2024-22414 is a vulnerability affecting the Flask-based blog application, flaskBlog. The issue lies in the improper handling of user comments on the `/user/<user>` page. Malicious comments containing arbitrary JavaScript code can be executed due to the use of the `|safe` tag in the `user.html` template, which disables content escaping. This vulnerability allows attackers to inject and run JavaScript code on affected pages. Users are advised to manually remove the `|safe` tag from the problematic code to mitigate the risk. Unfortunately, a fix is not currently available for this vulnerability.
