CVE-2025-23653

CVE-2025-23653 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the WordPress plugin Form To Online Booking (cf7-calendly-integration) by Nabeel Tahir. The issue affects all versions of the plugin from unknown initial release through 1.0 inclusive. Published on 2025-02-14, it 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), indicating high severity due to network accessibility and scope change.

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. Exploitation enables injection of arbitrary scripts into reflected web pages, potentially compromising the victim's browser session. This yields low impacts on confidentiality (e.g., session token theft), integrity (e.g., page modification), and availability, amplified by the changed scope to the user's context.
