The Yotpo: Product & Photo Reviews for WooCommerce plugin for WordPress suffers from a reflected cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the 'yotpo_user_email' and 'yotpo_user_name' parameters are not properly sanitized or escaped, allowing an attacker to inject malicious scripts that execute when a user interacts with a crafted URL. This vulnerability affects all versions up to and including 1.7.9. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability. No patch or official fix has been documented in the provided data.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of user credentials, session tokens, or other sensitive information accessible to the browser. The vulnerability requires user interaction (clicking a malicious link) and affects confidentiality and integrity to a limited extent. There is no reported impact on system availability. No known active exploitation has 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 untrusted links involving the affected plugin parameters. Consider disabling or removing the plugin if feasible or applying web application firewall (WAF) rules to block suspicious requests targeting 'yotpo_user_email' and 'yotpo_user_name' parameters. Monitor vendor channels for updates and apply patches promptly once released.
