At a glance

CVE-2021-25009 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the CorreosExpress WordPress plugin, affecting versions <= 2.6.0.

No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2021, reported by José Aguilera.

Vulnerability Overview

The CorreosExpress WordPress plugin through 2.6.0 generates log files which are publicly accessible, and contain sensitive information such as sender/receiver names, phone numbers, physical and email addresses

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 CorreosExpress <= 2.6.0 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. No fixed build of this plugin is recorded for CorreosExpress yet, so installs running <= 2.6.0 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
