Summary
Vulnerability in org.xwiki.contrib.blog:application-blog-ui (CVE-2025-66024). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 9.15.7 or later.
Original description
The description as published by the source.
Impact
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:
- Log in as a user with rights to create blog posts.
- Create a new blog post.
- In the Title field, insert the following payload designed to break out of the title tag:
alert('XSS in title blog') - Save (Publish) the post.
- View the post in the blog home page
Patches
The vulnerability has been patched in the blog application version 9.15.7 by adding missing escaping.
Workarounds
We're not aware of any workarounds.
