What is known
The Kaswara Modern VC Addons plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 3.0.1 due to insufficient capability checking on various AJAX actions.

Business impact
Successful exploitation of CVE-2021-4448, a high vulnerability (CVSS 7.3) affecting kaswara, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
