Browser script execution via reflected request input
Published Sep 27, 2023 · Updated Apr 28, 2026
Reflected XSS in Estatik Mortgage Calculator 2.0.7 and earlier allows remote attackers to execute script in a visitor's browser. The public advisory does not identify the request parameter, rendering function, or code path that reflects unneutralized input into the page. Exploitation requires a visitor to open an attacker-crafted request; the resulting script runs in the site's origin and can read or alter data available to that browser session.
