Summary

The Entity Embed module provides a filter to allow embedding entities in content fields. In certain circumstances, the filter could allow an unprivileged user to inject HTML into a page when it is accessed by a trusted user with permission to embed entities. In some cases, this could lead to cross-site scripting.
