Vulnerability Overview
The Email Newsletter for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 8.0. This made it possible for unauthenticated attackers to extract sensitive data such as user emails.
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. A successful exploit has high impact on confidentiality.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Reaching this weakness in Email Newsletter <= 8.0 takes a caller who can reach the endpoint. 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 Email Newsletter the fix is 9.0: builds <= 8.0 are affected, anything from 9.0 onward is not.
Remediation
Update to version 9.0, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: Email Newsletter 9.0 closes this, and updating the plugin is the step that ends it.
