The exports informed WordPress about the issue three months ago, however, the latter didn’t reply. It was then that Yibelo published the findings publically on a tech blogpost.
Attacks may happen in two situations: First, websites that don’t use WordPress primarily but have a WordPress endpoint on the same domain or subdomain. Second, a WordPress-hosted website that uses a CSP header.
