The vulnerability identified as CVE-2025-30935 affects the NickDuncan Contact Form plugin, specifically versions up to 2.0.12. It is caused by improper neutralization of input during web page generation, resulting in a DOM-based Cross-site Scripting (XSS) flaw. This allows an attacker with low privileges and requiring user interaction to execute malicious scripts in the context of the victim's browser session. The CVSS 3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, and partial 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 information, modification of data, or disruption of service related to the affected Contact Form plugin. The impact is limited by the requirement for user interaction and the attacker's need for low privileges.
