CVE-2026-39338: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ChurchCRM CRM
ChurchCRM is an open-source church management system. Prior to 7.1.0, a Blind Reflected Cross-Site Scripting vulnerability exists in the search parameter accepted by the ChurchCRM dashboard. The application fails to sanitize or encode user-supplied input prior to rendering it within the browser's DOM. Although the application ultimately returns an HTTP 500 error due to the malformed API request caused by the payload, the browser's JavaScript engine parses and executes the injected <script> tags before the error response is returned — resulting in successful code execution regardless of the server-side error. This vulnerability is fixed in 7.1.0.
AI Analysis
Technical Summary
ChurchCRM versions before 7.1.0 contain a Blind Reflected Cross-Site Scripting vulnerability in the dashboard's search parameter. The application does not sanitize or encode user-supplied input before rendering it in the browser DOM. Although the server responds with an HTTP 500 error due to malformed API requests caused by the payload, the injected JavaScript executes in the browser before the error is returned. This vulnerability is addressed in ChurchCRM version 7.1.0.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the victim's browser when they interact with the vulnerable search parameter. This can lead to session hijacking, unauthorized actions, or other malicious activities within the user's session. The CVSS 4.0 score of 8.6 reflects high impact with network attack vector, no privileges required, and user interaction needed.
Mitigation Recommendations
Upgrade ChurchCRM to version 7.1.0 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are indicated. Patch status is not explicitly stated beyond the fix in 7.1.0, so users should verify with vendor advisories for the latest guidance.
