The WordPress GDPR plugin is a tool designed to assist website owners in complying with EU data protection regulations by providing features such as user data access and deletion. This plugin is widely used and installed on a large number of websites, indicating its importance in the current digital landscape.
However, a vulnerability has been recently detected in this product, identified as CVE-2022-0220. This vulnerability results from the check_privacy_settings AJAX action not including an "application/json" content-type in its JSON data response. Additionally, the HTML payload is not properly escaped, leaving it open to interpretation by a web browser.
When exploited, this vulnerability could allow attackers to execute Javascript code on the victim's browser, potentially leading to the theft of sensitive information such as login credentials, payment information, and other personal data. This vulnerability is of particular concern for unauthenticated users, as they share the same nonce, rendering them more susceptible to attack.
