WordPress vulnerability analysis and mitigation

The Visual Form Builder WordPress plugin before version 3.0.7 contains a Cross-Site Scripting (XSS) vulnerability identified as CVE-2022-1046. The vulnerability was discovered and publicly disclosed on April 7, 2022. The issue affects the plugin's 'Email to' field, which lacks proper sanitization and escaping mechanisms (WPScan Advisory).

The vulnerability stems from improper sanitization and escaping of the form's 'Email to' field, enabling Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed. The vulnerability has been assigned a CVSS v3.1 base score of 4.8 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N. It is classified as CWE-79: Improper Neutralization of Input During Web Page Generation (NVD).

When exploited, this vulnerability allows high-privilege users to perform Cross-Site Scripting attacks. The impact is considered medium severity due to the requirement of high privileges and user interaction for successful exploitation. The vulnerability could potentially lead to unauthorized script execution in the context of other users' browsers (WPScan Advisory).

The vulnerability has been patched in Visual Form Builder version 3.0.7. Users are advised to update to this version or later to mitigate the security risk (WPScan Advisory).
