CVE-2025-2479 is a reflected cross-site scripting vulnerability in the Easy Custom Admin Bar WordPress plugin by duogeek, affecting all versions up to and including 1.0. The vulnerability arises from improper neutralization of input in the 'msg' parameter, enabling unauthenticated attackers to inject and execute arbitrary web scripts in the context of a victim's browser when they click on a crafted link. This can lead to limited confidentiality and integrity impacts but does not affect availability. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity.

Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the context of a victim's browser session, potentially leading to theft of sensitive information or manipulation of web content. The impact is limited to confidentiality and integrity with no direct availability impact. 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 available, users should avoid clicking on suspicious links that could exploit the 'msg' parameter. Monitoring for updates from the plugin vendor or WordPress security channels is recommended to apply any forthcoming patches promptly.
