This vulnerability involves improper neutralization of input in the WordPress Event Manager, Event Calendar and Booking Plugin (eventin-pro) up to version 4.0.24, leading to stored cross-site scripting (XSS). An attacker with low privileges can inject malicious scripts that execute when other users view the affected pages, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, and a scope change. No patch or vendor advisory details are provided, and the product is not a cloud service.

Successful exploitation allows an attacker with low privileges to inject stored malicious scripts that execute in the context of other users viewing the affected web pages. This can lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. The medium severity rating reflects these impacts. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting user input capabilities and applying web application firewall (WAF) rules to detect and block XSS payloads related to this plugin. Monitor vendor channels for updates and apply patches promptly once released.
