This vulnerability (CVE-2025-48333) affects WPQuark's eForm - WordPress Form Builder plugin versions before 4.19.1. It is caused by improper neutralization of input during web page generation, resulting in a reflected Cross-site Scripting (XSS) flaw. The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability. The vulnerability allows attackers to execute arbitrary scripts in the context of users interacting with the affected plugin's web pages.

Successful exploitation of this reflected XSS vulnerability can lead to execution of arbitrary scripts in users' browsers, potentially resulting in partial compromise of confidentiality, integrity, and availability of affected systems or user data. The CVSS vector indicates that an attacker can exploit this remotely without privileges but requires user interaction. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor WPQuark's official channels for updates. Until a fix is available, consider applying temporary mitigations such as disabling or restricting access to the vulnerable plugin functionality or employing web application firewall (WAF) rules to detect and block reflected XSS attempts targeting this plugin.
