Loan Comparison < 1.5.2 - Reflected XSS via shortcode

The plugin does not validate and escape some of its query parameters before outputting them back in a page/post via an embedded shortcode, which could allow an attacker to inject javascript into into the site via a crafted URL.

PoC

Create a page “Test” containing the shortcode “[loancomparison]”, then visit the page like this: https://example.com/test/?amount="//>
