Summary

The Easy Social Icons WordPress plugin before 4.0.3 does not sanitise SVG files, and it adds SVG to the file types that may be uploaded site-wide. Users with the Author role and above can upload an SVG containing XSS payloads (CWE-79). Where another installed Easy Social Icons WordPress plugin before 4.0.3 exposes an upload route to unauthenticated visitors, the same issue can be triggered without an account.
