The vulnerability identified as CVE-2025-26536 affects the Another Events Calendar plugin by Yendif Player, specifically versions up to 1.7.0. It is a reflected Cross-site Scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute when a victim accesses a crafted URL or input, potentially leading to unauthorized actions or data exposure within the affected web application context. The CVSS v3.1 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 affected web application, potentially leading to partial compromise of confidentiality, integrity, and availability of the affected system or user data. The reflected XSS nature means the attack requires user interaction (e.g., clicking a malicious link). There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and avoid clicking suspicious links related to the affected plugin. Monitor the vendor's communications for updates and apply patches promptly once available.
