CVE-2025-23471

CVE-2025-23471 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the WordPress plugin ECT Add to Cart Button (ect-add-to-cart-button) that enables Stored Cross-Site Scripting (XSS). The issue affects all versions of the plugin from its initial release through 1.4 inclusive. Published on 2025-01-16, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

Unauthenticated attackers (PR:N) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L), though it requires user interaction (UI:R) such as clicking a malicious link. Exploitation involves tricking a victim into submitting a CSRF request that stores an XSS payload, achieving low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L) but with a changed scope (S:C) due to the persistent nature of the stored script.
