What is CVE-2023-3179?

The POST SMTP Mailer Plugin for WordPress, specifically versions before 2.5.7, is susceptible to a Cross-Site Request Forgery (CSRF) vulnerability. This flaw arises due to inadequate CSRF checks in certain AJAX actions. As a result, attackers can exploit logged-in users who possess the manage_postman_smtp capability to send emails to unauthorized addresses. For instance, this could facilitate the unsolicited retransmission of sensitive emails, including password reset links, to an attacker-controlled email account, potentially leading to unauthorized account access and control.

Affected Version(s)

POST SMTP Mailer 2.5.0 < 2.5.7

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
