Summary

The POST SMTP Mailer plugin for WordPress, prior to version 2.5.7, contains a vulnerability where it lacks proper Cross-Site Request Forgery (CSRF) checks for certain AJAX actions. This flaw could lead to an attacker exploiting the plugin by tricking authenticated users who possess the manage_postman_smtp capability into unintentionally executing actions that result in the deletion of arbitrary logs. This unauthorized access poses significant risks to the integrity of user data and overall site security.

Affected Version(s)

POST SMTP Mailer 2.5.0 < 2.5.7

Exploit Proof of Concept (PoC)
