# Impact :
***********
WordPress Roberto Antonacci is vulnerable to cross-site request forgery, caused by
improper validation of user-supplied input. By persuading an authenticated user to visit
a malicious Web site, a remote attacker could send a malformed HTTP request to
perform unauthorized actions. An attacker could exploit this vulnerability to perform
cross-site scripting attacks, Web cache poisoning, and other malicious activities.
The web application does not, or can not, sufficiently verify whether a well-formed,
valid, consistent request was intentionally provided by the user who submitted the request.
When a web server is designed to receive a request from a client without any mechanism
for verifying that it was intentionally sent, then it might be possible for an attacker to trick a
client into making an unintentional request to the web server which will be treated as an
authentic request. This can be done via a URL, image load, XMLHttpRequest, etc. and
can result in exposure of data or unintended code execution.
