CVE-2025-58223 describes a stored cross-site scripting vulnerability in the VoucherPress plugin (versions <= 1.5.7) by Chris Taylor. The issue is caused by improper neutralization of input during web page generation, which allows an attacker with high privileges to inject malicious scripts that are stored and later executed when viewed by other users. The vulnerability has a CVSS 3.1 base score of 5.9, reflecting a medium severity with network attack vector, low attack complexity, required privileges, and user interaction. There is no vendor advisory or patch information provided, and no known exploitation in the wild has been reported.

Successful exploitation of this vulnerability could allow an attacker with high privileges to inject and store malicious scripts that execute in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. Because it is a stored XSS, the malicious payload can persist and affect multiple users. However, exploitation requires user interaction and elevated privileges, which limits the overall risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to trusted users only and apply input validation or sanitization controls where possible to reduce the risk of stored XSS. Monitor for updates from the vendor regarding patches or official mitigations.
