CVE-2025-23605

CVE-2025-23605 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the Call To Action Popup plugin (call-to-action-popup) for WordPress developed by lampd. This issue affects all versions of the plugin from n/a through 1.0.2 inclusive. The vulnerability was published on 2025-01-22 and carries 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).

Attackers can exploit this vulnerability remotely over the network with low attack complexity and no required privileges, though it demands user interaction such as visiting a maliciously crafted link or page. Upon successful exploitation, reflected XSS allows injection of arbitrary scripts into dynamically generated web pages viewed by authenticated users, potentially compromising low levels of confidentiality, integrity, and availability. The changed scope (S:C) indicates impact extends beyond the vulnerable component, enabling theft of session cookies, keystroke logging, or phishing within the context of the WordPress site.
