Vulnerability Overview

Unspecified vulnerability in the MailPoet Newsletters (wysija-newsletters) plugin before 2.6.8 for WordPress has unspecified impact and attack vectors.

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 privileges on the target site, and no interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in MailPoet Newsletters (Previous) <= 2.6.7 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For MailPoet Newsletters (Previous) the fix is 2.6.8: builds <= 2.6.7 are affected, anything from 2.6.8 onward is not.

Remediation

Update to version 2.6.8, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: MailPoet Newsletters (Previous) 2.6.8 closes this, and updating the plugin is the step that ends it.
