This vulnerability in WooCommerce Parcelas (<= 1.3.5) arises from improper neutralization of input during web page generation, enabling DOM-based Cross-site Scripting (XSS). The CVSS 3.1 score is 5.9 (medium), reflecting network attack vector, low attack complexity, requirement for high privileges and user interaction, and impacts on confidentiality, integrity, and availability. No known exploits are reported in the wild. The vendor has not provided a patch or advisory at this time.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to execute arbitrary scripts in the context of the affected web application, potentially leading to limited disclosure or modification of information and partial disruption of service.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should limit exposure by restricting high privilege access and exercising caution with user interactions involving this plugin.
