Vulnerability Overview

The Shortcodes Ultimate for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 5.12.7 via its shortcodes. This can allow authenticated attackers with subscriber-level privileges or higher to extract sensitive data including user meta information.

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. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Shortcodes Ultimate <= 5.12.7 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 Shortcodes Ultimate the fix is 5.12.8: builds <= 5.12.7 are affected, anything from 5.12.8 onward is not.

Remediation

Update to version 5.12.8, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Shortcodes Ultimate 5.12.8 closes this, and updating the plugin is the step that ends it.
