• Severity: medium (CVSS 6.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-04-22 · updated 2026-06-17
• Weakness: CWE-79

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.
