description

User Frontend WordPress plugin versions before 4.3.14 are affected by reflected cross-site scripting in a publicly accessible AJAX response. An attacker may cause script to run in the browser of a logged-out visitor if the request satisfies the anonymous nonce check.

mitigation

Update the User Frontend WordPress plugin to version 4.3.14 or later. Until updating, restrict public access to the affected AJAX functionality where operationally feasible.

fixed in 4.3.14
