This vulnerability (CVE-2026-56014) is an unauthenticated Cross-Site Scripting (XSS) issue in Averta Master Slider versions <= 3.11.2. It arises from improper neutralization of input during web page generation (CWE-79), enabling attackers to inject malicious scripts that execute in the context of the victim's browser. 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. No vendor advisory or patch information is available at this time.

Successful exploitation can allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to data theft, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The vulnerability is exploitable remotely without authentication, but requires user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider applying web application firewall (WAF) rules to detect and block XSS payloads targeting the Master Slider plugin. Avoid exposing vulnerable versions publicly and monitor for any updates from Averta regarding patches or mitigations.
