CVE-2023-6922Network attack vector

Subscriber data disclosure via unrestricted AJAX handler

Published Feb 28, 2024 · Updated Apr 8, 2026

Sensitive information exposure in Under Construction / Maintenance Mode 2.6 and earlier allows remote authenticated users to read subscriber data. The acx_csma_subscribe_ajax handler exposes stored subscription records to subscriber-level AJAX requests rather than restricting retrieval to administrators. A valid low-privilege account is required; the reported consequence is read-only disclosure of subscriber names and email addresses.
