The plugin does not sanitise or escape the sub-title field (available only with classic editor) when output in the page, which could allow users with a role as low as contributor to perform Cross-Site Scripting attacks
(The classic editor plugin is needed to see the sub-title field) - Create a post as contributor+ - Add the following payload in the sub-title field: <script>alert(/XSS/)</script> - View/preview the post to trigger the XSS
