CVE-2025-32551 is a reflected cross-site scripting vulnerability in the Jaap Jansma Connector to CiviCRM with CiviMcRestFace (versions <= 1.0.8). The issue stems from improper input neutralization during web page generation, enabling attackers to inject and execute malicious scripts in users' browsers. This can lead to partial compromise of confidentiality, integrity, and availability of affected systems or user sessions. The vulnerability has a CVSS 3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. No official patch or vendor advisory is currently available, and no known exploitation has been reported.

Successful exploitation of this reflected XSS vulnerability could allow attackers to execute arbitrary scripts in the context of users visiting affected web pages, potentially leading to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The CVSS score reflects a high severity with partial impact on these security properties. However, no known exploits are reported in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and exercise caution with user input handling. Monitor vendor channels for updates and apply patches promptly once available.
