Summary

The Easy Social Icons WordPress plugin does not sanitise uploaded SVG files, so a user with the Author role or higher can upload an SVG containing malicious scripts that run cross-site scripting attacks when the file is viewed. Where another Easy Social Icons plugin exposes an upload route to unauthenticated visitors, the same flaw can be triggered without an account.

Read the original description

The Easy Social Icons WordPress plugin before 4.0.3 does not sanitise SVG files, which it adds to the list of file types that may be uploaded site-wide, allowing users with the Author role and above to upload a malicious SVG containing XSS payloads. 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.
