## Description

A Cross-Site Scripting (XSS) was discovered in pi-engine/pi 2.5.0. The vulnerability exists due to insufficient filtration of user-supplied data (preview) passed to the "pi-develop/www/script/editor/markitup/preview/markdown.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

## What to do
