What is known
The HTML Forms WordPress plugin before 1.3.33 does not sanitize and escape the form message inputs, allowing high-privilege users, such as administrators, to perform Stored Cross-Site Scripting (XSS) attacks even when the unfiltered_html capability is disabled.
Business impact
Successful exploitation of CVE-2024-6243, a medium vulnerability (CVSS 4.8) affecting html forms, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
