CVE-2025-24660 is a reflected cross-site scripting (XSS) vulnerability stemming from improper neutralization of input during web page generation in the WordPress plugin Simple Membership Custom Messages (simple-membership-custom-messages, also referenced as wp.insider Simple Membership Custom Messages). The issue affects all versions of the plugin up to and including 2.4 and is classified under CWE-79 with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

Unauthenticated attackers can exploit this vulnerability remotely with low complexity by tricking users into interacting with maliciously crafted links or inputs that reflect executable scripts back in the web page. Exploitation requires user interaction, such as clicking a link, but changes the scope to the victim's browser context, potentially allowing limited impacts like low-level disclosure of sensitive data in cookies or session tokens, minor integrity modifications, or restricted denial of service.
