Present day versions of WordPress are susceptible to a saved XSS. An unauthenticated attacker can inject JavaScript in WordPress comments. The script is triggered while the comment is regarded.

If brought about with the aid of a logged-in administrator, beneath default settings the attacker can leverage the vulnerability to execute arbitrary code at the server via the plugin and subject matter editors.

Alternatively the attacker should exchange the administrator’s password, create new administrator accounts, or do something else the currently logged-in administrator can do on the target machine.
