The vulnerability CVE-2026-24988 in The Events Calendar Shortcode & Block plugin allows stored cross-site scripting due to improper input neutralization during web page generation. This enables attackers with at least low privileges and user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability of the affected system. The issue affects all versions up to 3.1.1. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope changed, with partial impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to data disclosure, modification, or disruption of service. The CVSS score of 6.5 reflects a medium severity impact on confidentiality, integrity, and availability. 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. Since no patch or official fix information is provided, users should monitor the vendor's communications for updates. Until a fix is available, minimizing exposure by restricting privileges and limiting user interaction with untrusted content may reduce risk.
