The vulnerability identified as CVE-2025-68856 affects the Mopinion Feedback Form by keeswolters, specifically versions up to and including 1.1.1. It is a DOM-based Cross-site Scripting (XSS) flaw caused by improper neutralization of input during web page generation. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with low impact on availability. This vulnerability allows an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to information disclosure or manipulation of the application state. No patch or official fix information is available, and the product is not a cloud service.

Successful exploitation of this DOM-based XSS vulnerability can lead to limited confidentiality and integrity impacts, such as theft of user data or session tokens, and limited availability impact. The attacker can execute malicious scripts in the context of the affected web application, potentially leading to user impersonation or unauthorized actions. However, exploitation requires user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider implementing input validation and output encoding on their own if possible, and apply Content Security Policy (CSP) headers to mitigate the impact of DOM-based XSS. Monitor vendor channels for updates and apply patches promptly once available.
