WordPress link-import.php cross-site scripting
| wordpress-linkimport-xss (35720) |  Medium Risk |
Description:
WordPress is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the link-import.php script. An authenticated remote attacker with admin privileges or the _wponce Authentication Token could exploit this vulnerability using the opml_url parameter in a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
