What the vulnerability does
The Easy Email Subscription plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3. This is due to missing or incorrect nonce validation on the show_editsub_page() function. This makes it possible for unauthenticated attackers to delete arbitrary subscribers via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Easy Email Subscription versions 1.3 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without their knowledge or consent. The vulnerability requires user interaction—the admin must visit the attacker's page—and does not expose sensitive data, but can modify site settings or data.
What an attacker can do
Trick a logged-in admin into performing unwanted actions on the site by visiting a malicious webpage.
Potential impact on your site
Site settings or data could be altered without admin knowledge if an admin visits a malicious link while logged in.
Conditions required to exploit
Admin must be logged in and visit an attacker-controlled webpage; no special privileges or authentication required from attacker.
