CVE-2024-12405 is a reflected cross-site scripting vulnerability (CWE-79) in the Export Customers Data plugin for WordPress by fahadmahmood. The vulnerability exists in the handling of the 't' parameter, which lacks proper input sanitization and output escaping. This flaw allows unauthenticated attackers to inject malicious scripts that execute in the context of a victim's browser if they are tricked into clicking a crafted link. The vulnerability affects all versions up to and including 1.2.3. The CVSS 3.1 base score is 6.1 (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 confidentiality and integrity impacts with no availability impact. There is no indication of known exploits in the wild or an available patch at this time.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser, potentially resulting in information disclosure and integrity impacts such as session hijacking or unauthorized actions performed on behalf of the user. The vulnerability requires user interaction and does not grant direct system access or availability disruption.
