Vulnerability Overview
The Under Construction / Maintenance Mode from Acurax plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.6 via the 'acx_csma_subscribe_ajax' function.

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
Under Construction / Maintenance Mode from Acurax <= 2.6 carries this weakness at acx_csma_subscribe_ajax, and reaching it 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. No fixed build of this plugin is recorded for Under Construction / Maintenance Mode from Acurax yet, so installs running <= 2.6 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.
