Because of this, at Flywheel, we block XML-RPC access by default for all sites. The number of sites that still need to use XML-RPC has dropped significantly over the last few years since WordPress introduced a REST API. How does Flywheel protect my sites from XML-RPC attacks? If a popular post was linked to many times, this could also cause Denial of Service to the site. They are a way of alerting sites that a post has been linked to from another site. These brute force attacks can slow down the site significantly from repeated attempts and can have a similar effect as a Denial of Service attack using up server resources, causing a site to go down.Īnother non-attack issue that could come from allowing XML-RPC access is trackbacks and pingbacks.
