CVE-2026-115277WP User Frontend < 4.3.14 - Reflected XSS via 'field_attr' Parameter
Medium 4.7
In plain English
A medium-severity cross-site scripting in User Frontend from Unknown. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 7% of all known vulnerabilities).
Official description
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.
