The vulnerability CVE-2025-22530 involves improper neutralization of input in the PORTONE iamport-payment plugin, leading to stored cross-site scripting (XSS). This allows attackers with limited privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability. The affected versions include all versions up to 1.1.19. No patch or official remediation information is currently available.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The CVSS vector indicates network attack vector, low attack complexity, privileges required, user interaction required, and scope change, with low impact on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with input handling and consider implementing additional input validation or output encoding as a temporary mitigation. Monitor vendor communications for updates on patches or official fixes.
