Vulnerability Overview

The Mail Mint – Email Marketing, Newsletter, Email Automation & WooCommerce Emails plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.19.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract sensitive user or configuration data.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Mail Mint <= 1.19.5 takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Mail Mint the fix is 1.20.0: builds <= 1.19.5 are affected, anything from 1.20.0 onward is not.

Remediation

Update to version 1.20.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Mail Mint 1.20.0 closes this, and updating the plugin is the step that ends it.
