CVE-2025-22635 is a reflected cross-site scripting vulnerability in the imithemes Eventer plugin (versions before 3.9.9). It results from improper input neutralization during web page generation, enabling attackers to inject malicious scripts that execute when a user interacts with crafted content. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the context of the victim's browser session. This may lead to partial disclosure of sensitive information, modification of web page content, or disruption of availability. The CVSS vector indicates that the attack can be performed remotely without privileges but requires user interaction.
