Summary
The WP User Frontend plugin for WordPress is affected, allowing an attacker to inject malicious scripts through a crafted request that get reflected back in a page's HTML. When a logged-out visitor opens such a link, the script runs in their browser, which could be used to steal information or perform actions on the site as that visitor.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original 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.
