The Arevico WP Simple Redirect plugin for WordPress versions up to 1.1 suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers to craft malicious URLs that, when visited by users, execute arbitrary scripts in their browsers. The CVSS v3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the victim's browser, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data. The reflected nature means the attack requires user interaction (clicking a crafted link). There are no known exploits in the wild at this time.

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 URLs involving the WP Simple Redirect plugin and consider disabling or removing the plugin if feasible. Monitor vendor channels for updates regarding patches or official mitigations.
