## Affected

## Description

The Simple Like Page Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'sfp-page-plugin' shortcode in versions up to, and including, 1.5.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
