The AtaraPay WooCommerce Payment Gateway plugin suffers from an improper neutralization of input during web page generation, resulting in a reflected cross-site scripting vulnerability. This flaw affects all versions up to 2.0.13 and allows attackers to inject malicious scripts that execute in the context of the victim's browser when they interact with crafted web pages generated by the plugin. The vulnerability is remotely exploitable without privileges and requires user interaction. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts confidentiality, integrity, and availability at a low level.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website, potentially allowing attackers to steal user credentials, perform actions on behalf of users, or disrupt availability. The impact affects confidentiality, integrity, and availability at a low level but is considered high severity due to the ease of exploitation and the scope change.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the AtaraPay WooCommerce Payment Gateway plugin if possible or applying any available temporary mitigations recommended by the vendor. Monitoring for updates from the vendor is strongly advised.
