The WP FixTag plugin for WordPress, developed by mohsenshahbazi, contains a reflected cross-site scripting vulnerability (CVE-2025-23564) due to improper input neutralization during web page generation. This vulnerability affects all versions up to 2.0.2. An attacker can craft a malicious URL or input that, when processed by the plugin, results in arbitrary script execution in the victim's browser. The CVSS 3.1 base score is 7.1 (high), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability allows an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability to a limited extent. 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. Since no patch or official fix information is provided, users should monitor for updates from the plugin developer or WordPress plugin repository. As a temporary measure, consider disabling or removing the WP FixTag plugin if it is not essential, or apply web application firewall (WAF) rules to detect and block reflected XSS attempts targeting this plugin.
