This vulnerability involves improper neutralization of input in the Contact Form 7 – PayPal & Stripe Add-on, which leads to stored cross-site scripting (XSS). The flaw allows an attacker with high privileges and requiring user interaction to inject malicious scripts that can compromise confidentiality, integrity, and availability to a limited extent. The affected versions include all versions up to 2.3.4. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with low confidentiality, integrity, and availability impacts.

Successful exploitation could allow an attacker with high privileges and user interaction to execute stored malicious scripts within the context of the affected application, potentially leading to limited confidentiality, integrity, and availability impacts. However, the overall severity is medium, and no active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to high-privilege users and limit user interactions with untrusted input in the affected add-on. Monitor vendor channels for updates and apply patches promptly once released.
