CVE-2026-40483: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ChurchCRM CRM
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the Pledge Editor renders donation comment values directly into HTML input value attributes without escaping via htmlspecialchars(). An authenticated user with Finance permissions can inject HTML attribute-breaking characters and event handlers into the comment field, which are stored in the database and execute in the browser of any user who subsequently opens the pledge record for editing, resulting in stored XSS. This issue has been fixed in version 7.2.0.
AI Analysis
Technical Summary
ChurchCRM CRM versions before 7.2.0 suffer from a stored XSS vulnerability (CWE-79) due to improper neutralization of input in the Pledge Editor. Specifically, donation comment fields are inserted into HTML input value attributes without escaping via htmlspecialchars(), allowing authenticated Finance users to inject malicious HTML and JavaScript code. This code executes in the context of any user who subsequently opens the affected pledge record for editing. The vulnerability is addressed in ChurchCRM version 7.2.0.
Potential Impact
Successful exploitation allows an authenticated user with Finance permissions to execute arbitrary scripts in the browsers of other users who open the affected pledge records. This can lead to information disclosure or session hijacking within the scope of the affected application. The CVSS 3.1 base score is 5.4 (medium severity), reflecting the need for authentication and user interaction but the potential for impact on confidentiality and integrity.
Mitigation Recommendations
This vulnerability is fixed in ChurchCRM version 7.2.0. Users should upgrade to version 7.2.0 or later to remediate this issue. No official patch or workaround is indicated beyond upgrading. Since this is not a cloud service, remediation depends on applying the update.
