Description

The CUBA REST API add-on performs operations on data and entities. Prior to version 7.2.7, the input parameter, which consists of a file path and name, can be manipulated to return the Content-Type header with text/html if the name part ends with .html. This could allow malicious JavaScript code to be executed in the browser. For a successful attack, a malicious file needs to be uploaded beforehand. This issue has been patched in version 7.2.7. A workaround is provided on the Jmix documentation website.

Attack-Flow Graph

Executive Summary

CVE-2025-32960 is a cross-site scripting (XSS) vulnerability in the /files endpoint of the CUBA REST API add-on. The issue occurs when the input parameter—composed of a file path and a file name—is manipulated so that if the file name ends with '.html', the service returns a Content-Type header of text/html. This behavior may allow malicious JavaScript code to be executed in the victim's browser if a malicious file has been uploaded beforehand. The problem is fixed in version 7.2.7 and, alternatively, the Files Endpoint can be disabled as a workaround. [4]

Impact Analysis

If you interact with a system using the affected CUBA REST API add-on, an attacker might manipulate file names to trigger a cross-site scripting attack, potentially resulting in unauthorized execution of malicious JavaScript in your browser. However, the impact is mitigated by the fact that access to the API and the application's UI is generally restricted to authenticated users, which reduces the overall exposure. [4]

Mitigation Strategies

To mitigate the vulnerability, upgrade to version 7.2.7 of the CUBA REST API add-on where the issue is patched. If upgrading is not possible, apply the recommended workaround by disabling the Files Endpoint as described in the Jmix documentation. [1, 2]
