CVE-2026-34900 is an unauthenticated cross-site scripting (XSS) vulnerability in the GiveWP plugin for WordPress, affecting versions up to 4.14.2. The issue 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, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of users visiting the affected GiveWP installation. This may lead to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The vulnerability is exploitable without authentication but requires user interaction.
