WordPress Plugin Vulnerabilities
Get Custom Field Values < 4.0.1 - Contributor+ Stored Cross-Site Scripting
Description
The plugin does not escape custom fields before outputting them in the page, which could allow users with a role as low as contributor to perform Cross-Site Scripting attacks
Proof of Concept
As a contributor, create a custom field in a post, with the following payload: <script>alert(1)</script> Then add the following shortcode to the post: [custom_field field="<custom_field_name>"]
