The vulnerability identified as CVE-2025-46487 affects the sftranna EC Authorize.net plugin (versions up to 0.3.3). It is a reflected Cross-site Scripting (XSS) flaw caused by improper neutralization of input during web page generation. This allows attackers to inject malicious scripts that execute when a victim interacts with crafted web content. The CVSS 3.1 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 vendor advisory or patch information currently available, and no known exploits in the wild have been reported.

Successful exploitation of this reflected XSS vulnerability can allow an attacker to execute arbitrary scripts in the context of the victim's browser session. This may lead to partial disclosure of sensitive information, modification of data, or disruption of service availability related to the affected plugin's web interface. The CVSS score reflects a high impact on confidentiality, integrity, and availability, but exploitation requires user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts and avoid clicking on suspicious links that may exploit this vulnerability.
