The vulnerability CVE-2025-23852 affects robin90's First Comment Redirect plugin versions up to 1.0.3. It is a reflected cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in users' browsers when they interact with crafted URLs or inputs. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and no exploits are known in the wild.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability as indicated by the CVSS vector. However, no known exploits are currently reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts and avoid using affected versions of the plugin. Monitor vendor channels for updates and apply patches promptly once available.
