WordPress vulnerability analysis and mitigation

The CVE-2022-4309 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WordPress plugin Subscribe2 versions prior to 10.38. The vulnerability was discovered and publicly disclosed on December 22, 2022. This security flaw affects the user deletion functionality in the Subscribe2 plugin, which is commonly used for email subscriptions and newsletters in WordPress installations (WPScan).

The vulnerability stems from the absence of CSRF protection mechanisms in the user deletion functionality of the Subscribe2 plugin. It has been assigned a CVSS score of 7.1 (High) and is classified under CWE-352. The vulnerability falls under the OWASP Top 10 category A2: Broken Authentication and Session Management (WPScan).

When exploited, this vulnerability allows attackers to trick authenticated administrators into deleting arbitrary users from the WordPress installation by knowing their email addresses. However, there is a limitation where attackers cannot delete the user account that is currently being used to execute the CSRF attack (WPScan).

The vulnerability has been fixed in Subscribe2 version 10.38. Users are strongly advised to update their Subscribe2 plugin to this version or later to mitigate the risk (WPScan).
