CVE-2021-33849
A Cross-Site Scripting (XSS) attack can cause arbitrary code (JavaScript) to run in a user’s browser while the browser is connected to a trusted website.
Does this matter?
Lower severity and a low EPSS score (1.08%). Track it; it rarely justifies an emergency change on its own.
Description
A Cross-Site Scripting (XSS) attack can cause arbitrary code (JavaScript) to run in a user’s browser while the browser is connected to a trusted website. The attack targets your application's users and not the application itself while using your application as the attack's vehicle. The XSS payload executes whenever the user changes the form values or deletes a created form in Zoho CRM Lead Magnet Version 1.7.2.4.
