WordPress Plugin Vulnerabilities
WPeMatico RSS Feed Fetcher < 2.6.12 - Admin+ Stored Cross-Site Scripting
Description
The plugin does not escape the Feed URL added to a campaign before outputting it in an attribute, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
Proof of Concept
Create/edit a campaign and add the following feed URL: https://wordpress.com/#"><script>alert('xss')</script>
The XSS will be triggered when editing the campaign again or run it.
