CVE-2025-30547 describes a reflected cross-site scripting vulnerability in the WP Cards WordPress plugin by David Tufts. The issue is due to improper input neutralization during web page generation, allowing attackers to inject and execute malicious scripts in users' browsers. This affects all versions up to 1.5.1. The vulnerability has a CVSS 3.1 score of 7.1, with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and no known exploitation has been reported.

Successful exploitation of this vulnerability could allow attackers to execute arbitrary scripts in the context of users visiting affected sites, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The reflected nature means the attack requires user interaction, such as clicking a crafted link.

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 WP Cards plugin if feasible. Employing web application firewalls (WAFs) that can detect and block reflected XSS attempts may provide temporary mitigation.
