CVE-2025-66024: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in xwiki-contrib application-blog-ui
The XWiki blog application allows users of the XWiki platform to create and manage blog posts. Versions starting with 9.15 and prior to 9.15.7 are 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 <title> 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. The vulnerability has been patched in the blog application version 9.15.7 by adding missing escaping. No known workarounds are available.

Technical Summary
The xwiki-contrib application-blog-ui contains a stored XSS vulnerability (CWE-79) identified as CVE-2025-66024. The vulnerability arises from improper neutralization of input in the blog post title field, which is directly injected into the HTML <title> tag without escaping.

Potential Impact
Successful exploitation allows an attacker with blog post creation or editing rights to execute arbitrary JavaScript in the context of users viewing the blog post, including administrators. This can result in session hijacking or privilege escalation. The vulnerability affects confidentiality and integrity of user sessions and potentially the application environment.
Mitigation Recommendations
An official patch is available in application-blog-ui version 9.15.7 that fixes the vulnerability by adding proper escaping to the blog post title. Users should upgrade to version 9.15.7 or later to remediate this issue. No workarounds are currently known.
