WordPress Plugin Vulnerabilities

Google CSE <= 1.0.7 - Admin+ Stored XSS

Description

The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

Proof of Concept

1. Go to https://example.com/wp-admin/options-general.php?page=google-cse-options
2. Enter the payload `da"><script>alert(1)</script>` for either input and save
3. See the XSS
