info:
|
|
name: WordPress GDPR & CCPA < 1.9.27 - Unauthenticated Reflected Cross-Site Scripting
|

author: daffainfo

severity: medium

description: |
|
|
The check_privacy_settings AJAX action of the WordPress GDPR WordPress plugin before 1.9.27, available to both unauthenticated and authenticated users, responds with JSON data without an "application/json" content-type. Since an HTML payload isn't properly escaped, it may be interpreted by a web browser led to this endpoint. Javascript code may be executed on a victim's browser. Due to v1.9.26 adding a CSRF check, the XSS is only exploitable against unauthenticated users (as they all share the same nonce)
