Security Summary

CVE-2025-23852 is an improper neutralization of input during web page generation vulnerability, enabling reflected cross-site scripting (XSS) as defined by CWE-79, in the First Comment Redirect WordPress plugin developed by robin90. This issue affects the plugin from its initial release through version 1.0.3.

The vulnerability carries a CVSS v3.1 base score of 7.1 (High) with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L. Remote attackers require no privileges and face low attack complexity but must trick users into interacting, such as via a malicious link or comment. Exploitation reflects attacker-controlled input as executable scripts in the victim's browser, with changed scope enabling low-level impacts on confidentiality, integrity, and availability, such as limited data theft or page manipulation.
