Email Subscribers & Newsletters <= 5.3.1 - Authenticated (or Cross-Site Request Forgery) Blind SQL Injection

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2022-0439
CVSS High (8.8)
Publicly Published February 11, 2022
Last Updated January 22, 2024
Researcher Krzysztof Zając
Description

The Email Subscribers & Newsletters WordPress plugin before 5.3.2 does not correctly escape the `order` and `orderby` parameters to the `ajax_fetch_report_list` action, making it vulnerable to blind SQL injection attacks by users with roles as low as Subscriber. Further, it does not have any CSRF protection in place for the action, allowing an attacker to trick any logged in user to perform the action by clicking a link.
