## Technical details

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Unauthenticated Reflected Cross-Site Scripting (XSS) due to improper neutralization of input during web page generation (CWE-79). An unauthenticated attacker can send a specially crafted request to a vulnerable site, which, if executed by a victim (typically an administrator or site visitor), allows the attacker to run arbitrary JavaScript in the context of the victim's browser. This can lead to session hijacking, unauthorized actions on behalf of the user, or the delivery of malicious payloads. The vulnerability is present in versions up to and including 5.110.1 and was addressed in version 5.111.0.
