The vulnerability CVE-2025-23655 affects the Contact Form 7 – Paystack Add-on by crystalwebpro, specifically versions up to 1.2.3. It is a reflected Cross-site Scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in users' browsers when they interact with the vulnerable contact form. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope change, and low impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to theft of user data, session hijacking, or other malicious actions. The CVSS score indicates limited but non-negligible impacts on confidentiality, integrity, and availability. There are no known exploits in the wild at this time.
