The vulnerability CVE-2025-30963 affects Crocoblock JetSmartFilters versions up to 3.6.3 and involves improper neutralization of input during web page generation, resulting in a DOM-based Cross-site Scripting (XSS) issue. This allows an attacker with at least low privileges and requiring user interaction to potentially 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 at a low level.

Successful exploitation of this DOM-based XSS vulnerability could allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to partial disclosure of information, modification of data, or disruption of service within the affected application context. The impact is rated as medium severity with low-level confidentiality, integrity, and availability impacts.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround information is provided, users should monitor Crocoblock's advisories for updates. Until a fix is available, consider restricting access to the affected component or applying input validation and output encoding controls where possible to mitigate DOM-based XSS risks.
