CVE-2026-109701: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in PAYCOMET PAYCOMET for WooCommerce

The vulnerability CVE-2026-109701 affects PAYCOMET for WooCommerce (paytpv-for-woocommerce) and is characterized by improper neutralization of input during web page generation, resulting in a reflected Cross-site Scripting (XSS) flaw. This allows attackers to inject malicious scripts that execute when a user interacts with crafted web content. The affected versions include all releases from the initial version through 5.45. The CVSS v3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. There is no information on known exploits in the wild or vendor-provided patches.

Successful exploitation of this reflected XSS vulnerability can lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. Attackers may execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, defacement, or other malicious actions. However, no active exploitation has been reported.
