Low risk7th percentile - higher than 7% of all known CVEs
Summary
The User Frontend WordPress plugin before 4.3.14 does not sanitise and escape some user-supplied values before reflecting them into HTML attributes in a publicly reachable AJAX response, leading to Reflected Cross-Site Scripting. The affected action is gated by an anonymous nonce that only validates for logged-out requests, so the payload executes against logged-out visitors rather than authenticated users.
Risk Assessment
An attacker can trick a logged-out visitor into clicking a crafted link, allowing execution of a malicious script in their browser and theft of data or actions performed on their behalf.
Recommendation
Update the User Frontend plugin to version 4.3.14 or later. Inform users about the risk of clicking unknown links.
