WordPress Plugin Vulnerabilities
Simple Banner < 2.12.0 - Admin+ Stored Cross Site Scripting
Description
The plugin does not properly sanitize its "Simple Banner Text" Settings allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
Proof of Concept
Put the following payloads in the "Simple Banner Text" settings of the plugin: <a href="jav ascript:alert(document.cookie)">Firefox</a> <sc<script>ript>alert(/XSS/)</scr</script>ipt> Then access the frontend to trigger the XSS
