Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown User Profile Builder: fixed in 4.0.5

## Description

The User Profile Builder WordPress plugin before 4.0.5 does not sanitise and escape one of its shortcode attributes before outputting it back in a redirect message, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks against higher-privileged users who submit the affected form.
