CVE-2025-49321 describes a reflected cross-site scripting vulnerability in the Arraytics Eventin WordPress plugin (wp-event-solution) versions up to 4.0.28. The issue is caused by improper input sanitization during web page generation, enabling attackers to inject malicious scripts that execute when a user interacts 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 classified as low to low to low respectively. No patch or official fix information is available from the vendor or other sources at this time.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The reflected nature of the XSS requires user interaction to trigger the payload. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or limiting use of the affected plugin version. Employing web application firewalls (WAFs) that can detect and block reflected XSS attempts may provide temporary mitigation. Monitor vendor channels for updates and apply official patches promptly once released.
