CVE-2025-53994 describes a DOM-based Cross-site Scripting (XSS) vulnerability in Crocoblock JetPopup plugin versions up to 2.0.15. The issue arises from improper neutralization of user input during web page generation, which can allow an attacker with 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 (medium), reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, and partial impact 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 limited by the requirement for user interaction and low privileges, but the vulnerability affects confidentiality, integrity, and availability to some extent.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider limiting exposure by restricting access to the affected plugin and exercising caution with untrusted input. Monitor Crocoblock's official channels for updates and apply patches promptly once released.
