Vulnerability Overview

The SUMO Affiliates Pro plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.0.0. 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 SUMO Affiliates Pro <= 11.0.0 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 SUMO Affiliates Pro the fix is 11.1.0: builds <= 11.0.0 are affected, anything from 11.1.0 onward is not.

Remediation

Update to version 11.1.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: SUMO Affiliates Pro 11.1.0 closes this, and updating the plugin is the step that ends it.
