CVE-2024-11223: 
WordPress vulnerability analysis and mitigation

The WPForms WordPress plugin before version 1.9.2.3 contains a stored Cross-Site Scripting (XSS) vulnerability. The vulnerability was discovered on December 5, 2024, and affects the plugin's settings functionality. The issue stems from inadequate sanitization and escaping of certain settings, particularly impacting high-privilege users such as administrators (WPScan, NVD).

The vulnerability exists in the plugin's form creation functionality, specifically in the Number Slider field's Value Display settings. The issue occurs when the unfiltered_html capability is disallowed, which is common in multisite setups. The vulnerability has been assigned a CVSS score of 4.7 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L (NVD).

When exploited, this vulnerability allows high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks. This is particularly significant in multisite setups where the unfiltered_html capability is typically disallowed as a security measure (WPScan).

The vulnerability has been patched in WPForms version 1.9.2.3. Users are strongly advised to update to this version or later to mitigate the security risk (WPScan).
