The Blog Application is vulnerable to Stored Cross-Site Scripting (XSS) via the Blog Post Title. The vulnerability arises because the post title is injected directly into the HTML tag without proper escaping.
An attacker with permissions to create or edit blog posts can inject malicious JavaScript into the title field. This script will execute in the browser of any user (including administrators) who views the blog post. This leads to potential session hijacking or privilege escalation.
To reproduce:
</title><script>alert('XSS in title blog')</script>The vulnerability has been patched in the blog application version 9.15.7 by adding missing escaping.
We're not aware of any workarounds.
