Vulnerability Overview

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 Photo Gallery, Sliders, Proofing and Themes <= 2.2.46 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 Photo Gallery, Sliders, Proofing and Themes the fix is 2.2.50: builds <= 2.2.46 are affected, anything from 2.2.50 onward is not.

Remediation

Update to version 2.2.50, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Photo Gallery, Sliders, Proofing and Themes 2.2.50 closes this, and updating the plugin is the step that ends it.
