Deeper analysis

CVE-2026-23977 is a missing authorization vulnerability (CWE-862) in the WPFactory Helpdesk Support Ticket System for WooCommerce WordPress plugin, specifically allowing exploitation of incorrectly configured access control security levels. The issue affects all versions of the support-ticket-system-for-woocommerce plugin from n/a through 2.1.2.

Attackers require no privileges (PR:N) and can exploit the vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation results in high confidentiality impact (C:H) with no integrity (I:N) or availability (A:N) impact and unchanged scope (S:U), enabling unauthenticated remote access to sensitive information, as reflected in the CVSS v3.1 base score of 7.5.
