## Technical details

This is a stored cross-site scripting (XSS) vulnerability in the submission edit screen where form field values are output without proper escaping. An unauthenticated attacker can submit arbitrary HTML/JavaScript through a public form, which then executes in the browser of high-privileged users (administrators) when they review the submission in the WordPress admin area. The vulnerability affects version 3.15.3 and was patched in 3.15.4.
