XML-RPC is a protocol that enables remote procedure calls over the internet using XML. XML-RPC offers a convenient way to interact with web services and perform various operations. It is commonly used in WordPress to allow remote publishing and other functionalities. However, the XML-RPC functionality has also been known to introduce security vulnerabilities. To mitigate these risks, it is recommended to periodically test the XML-RPC functionality using tools like XML-RPC checkers. By conducting regular XML-RPC tests, WordPress administrators can ensure the secure operation of their websites and block unauthorized access to the XML-RPC endpoint if necessary.
