Vulnerability Overview

The Contest Gallery – Upload & Vote Photos, Media, Sell with PayPal & Stripe plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 28.1.7. 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 Contest Gallery <= 28.1.7 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 Contest Gallery the fix is 29.0.0: builds <= 28.1.7 are affected, anything from 29.0.0 onward is not.

Remediation

Update to version 29.0.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Contest Gallery 29.0.0 closes this, and updating the plugin is the step that ends it.
