How to Fix CVE-2025-66024

To remediate this vulnerability, upgrade all affected Application blog ui dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.xwiki.contrib.blog:application-blog-ui fixed: 9.15.7 
<dependency>
    <groupId>org.xwiki.contrib.blog</groupId>
    <artifactId>application-blog-ui</artifactId>
    <version>9.15.7</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.xwiki.contrib.blog

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-66024, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.xwiki.contrib.blog

Analyze the terminal output to locate any version of Application blog ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.15.7), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.xwiki.contrib.blog command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. In Application blog ui, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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 `<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. 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: ```</title><script>alert('XSS in title blog')</script>``` * 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. ### References * https://jira.xwiki.org/browse/BLOG-245 * https://github.com/xwiki-contrib/application-blog/commit/cca87f0a0edc2e7e049d46d51f4a4d8f78b714ba ### Attribution Łukasz Rybak reported this vulnerability.
