The vulnerability CVE-2025-23543 affects the fomopay FOMO Pay Chinese Payment Solution plugin for WooCommerce (versions up to 2.0.4). It is a reflected Cross-site Scripting (XSS) issue caused by improper neutralization of input during web page generation. This allows attackers to inject malicious scripts that can execute in the context of a victim's browser. The CVSS 3.1 base score is 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network exploitable with low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability with scope change. No patch or official fix information is currently available, and no known exploits have been reported.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of a user's browser session, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability as indicated by the CVSS vector. However, no known exploits in the wild have been reported to date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is released, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts. Monitor vendor channels for updates.
