WordPress Plugin Vulnerabilities

MailChimp Subscribe Forms < 4.0.9.8 - Editor+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting via settings due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
