WordPress Plugin Vulnerabilities

Gianism <= 5.1.0 - 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=gianism&view=setting
2. In the "URL Prefix" field, enter the payload `<img src=xss onerror=alert(1)>`
3. Save and see the XSS
