At a glance

CVE-2023-1263 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the CMP WordPress plugin, affecting versions <= 4.1.6. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.1.7; sites on affected versions should update now. Disclosed March 2023, reported by Marco Wotschka.

Vulnerability Overview

The CMP – Coming Soon & Maintenance plugin for WordPress is vulnerable to Information Exposure in versions up to, and including, 4.1.6 via the cmp_get_post_detail function. This can allow unauthenticated individuals to obtain the contents of any non-password-protected, published post or page even when maintenance mode is enabled.

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.

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

Reaching this weakness in CMP <= 4.1.6 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 CMP the fix is 4.1.7: builds <= 4.1.6 are affected, anything from 4.1.7 onward is not.

Remediation

Update to version 4.1.7, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: CMP 4.1.7 closes this, and updating the plugin is the step that ends it.
