CVE-2026-104404: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Liquid Web / StellarWP GiveWP

This vulnerability in GiveWP allows stored cross-site scripting due to improper input neutralization during web page generation. An attacker with low privileges and requiring user interaction can inject malicious scripts that compromise confidentiality, integrity, and availability to a limited extent. The affected versions are all versions prior to 4.18.0. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to data theft, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability. The impact is limited by the requirement for user interaction and low privileges, and the overall severity is medium.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting user input or applying web application firewall rules to detect and block malicious scripts related to this vulnerability.
