This vulnerability in ryan_xantoo Map Contact plugin (versions <= 3.0.4) involves CSRF that enables Stored XSS attacks. The CVSS 3.1 base score is 7.1 (High), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed with low impact on confidentiality, integrity, and availability. The issue allows attackers to trick authenticated users into submitting malicious requests that store executable scripts, potentially compromising user sessions or data.

Successful exploitation can lead to stored XSS, allowing attackers to execute arbitrary scripts in the context of the victim's browser. This can result in partial loss of confidentiality, integrity, and availability of the affected system or user data. The vulnerability requires user interaction and can be exploited remotely over the network without privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or restricting the use of the Map Contact plugin to trusted users only and apply standard CSRF mitigations if possible.
