CVE-2025-39450 describes a DOM-based Cross-site Scripting vulnerability in Crocoblock JetTabs plugin versions up to and including 2.2.7. The issue arises from improper neutralization of user input during web page generation, enabling an attacker with at least low privileges and requiring user interaction to execute malicious scripts in the context of the affected web application. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The impact is rated medium based on the CVSS score and the nature of DOM-based XSS.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
