The vulnerability CVE-2025-49951 in the wpcrunch gAppointments plugin 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 when a victim interacts with crafted content. The affected versions include all releases up to 1.14.1. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction needed, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The CVSS vector indicates partial impact on all three security properties. There are no known exploits in the wild at this time.

No official patch or remediation guidance is currently available for this vulnerability. Users of wpcrunch gAppointments should monitor the vendor's advisories for updates and apply any official fixes once released. Until then, consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts as a temporary mitigation.
