The vulnerability CVE-2025-46459 affects the Confirm User Registration plugin by Ralf Hortt. It is a stored cross-site scripting (XSS) issue caused by improper neutralization of input during web page generation. This allows an attacker with high privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The vulnerability affects versions up to 2.1.5. No patch or vendor advisory details are provided, and no known exploits have been observed.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change. However, no known exploits in the wild have been reported.

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 user input and consider applying temporary mitigations such as input validation or output encoding if feasible. Monitor the vendor's communications for updates on patches or official fixes.
