Vulnerability Overview

The Comments Import & Export plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions 2.1.11 to 2.5.3. This makes it possible for authenticated attackers, with author-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 Comments Import & Export 2.1.11 – 2.5.3 takes an account at Author 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 Comments Import & Export the fix is 2.5.4: builds 2.1.11 – 2.5.3 are affected, anything from 2.5.4 onward is not.

Remediation

Update to version 2.5.4, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Comments Import & Export 2.5.4 closes this, and updating the plugin is the step that ends it.
