This vulnerability involves improper neutralization of input in the CashBill.pl – Płatności WooCommerce plugin, leading to stored cross-site scripting (XSS). An attacker with high privileges and requiring user interaction could inject malicious scripts that are stored and later executed in the context of users viewing affected pages. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and impacts confidentiality, integrity, and availability at a low level. The issue affects versions up to 3.2.1 of the plugin. No official patch or fix has been documented in the provided data.

Successful exploitation could allow an attacker with high privileges to inject malicious scripts that execute when other users view affected pages, potentially leading to limited confidentiality, integrity, and availability impacts. The medium severity reflects the requirement for high privileges and user interaction, limiting the ease of exploitation. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high-privilege user access to trusted personnel only and exercise caution with user-generated content in the affected plugin. Monitor vendor channels for updates and apply patches promptly once released.
