Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
ChurchCRM is an open-source church management system. Prior to version 7.4.0, Cross-Site Scripting (XSS) vulnerabilities were identified due to insufficient output encoding of user-controlled request parameter names and parameter values. The application reflects attacker-controlled input into JavaScript string contexts and HTML attribute contexts without proper sanitization or contextual output encoding. Affected endpoints observed during testing: /FamilyCustomFieldsEditor.php, /PaddleNumList.php and /admin/system/church-info. Potential consequences include session-token theft, account takeover, unauthorized actions on behalf of authenticated users, exposure of sensitive church member information, credential harvesting, phishing, and privilege escalation when administrators are targeted. This issue has been resolved in version 7.4.0.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

ChurchCRM versions prior to 7.4.0 contain Reflected XSS vulnerabilities in multiple endpoints (/FamilyCustomFieldsEditor.php, /PaddleNumList.php, /admin/system/church-info) where user-controlled request parameter names and values are reflected into JavaScript string and HTML attribute contexts without proper output encoding or contextual sanitization, allowing injection of arbitrary script execution.

MitigationUpgrade to ChurchCRM version 7.4.0 or later, which implements proper output encoding; alternatively, apply contextual output encoding to all user-supplied input reflected into HTML/JavaScript contexts at the identified endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed ChurchCRM version
    Locate the version file or check the admin interface (typically System Dashboard or /public/version.php) to determine the running version
    Affected if The installed version is any version prior to 7.4.0
  2. Verify affected endpoints exist
    Check if the following PHP files exist in the web root: FamilyCustomFieldsEditor.php, PaddleNumList.php, and the file handling /admin/system/church-info
    Affected if Any of these endpoint files are present and accessible on the server
  3. Test parameter reflection in FamilyCustomFieldsEditor.php
    Submit a crafted request with a test parameter (e.g., ?test=<script>alert(1)</script>) and inspect if the parameter name or value appears unencoded in the page response HTML or JavaScript
    Affected if User-supplied parameter names or values are reflected into the response without HTML encoding or JavaScript escaping
  4. Test parameter reflection in PaddleNumList.php
    Submit a crafted request with a test parameter and inspect the response for unencoded output in HTML attributes or JavaScript string contexts
    Affected if User-supplied parameter names or values are reflected into the response without HTML encoding or JavaScript escaping
  5. Test parameter reflection in admin/system/church-info
    Submit crafted parameters to the church-info endpoint and examine if input is reflected without contextual encoding in HTML or JavaScript contexts
    Affected if User-supplied parameter names or values are reflected into the response without HTML encoding or JavaScript escaping

The environment is affected if ChurchCRM version is below 7.4.0 AND any of the three vulnerable endpoints reflect user-controlled input without proper output encoding in HTML or JavaScript contexts.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to ChurchCRM version 7.4.0 or later, which implements proper output encoding; alternatively, apply contextual output encoding to all user-supplied input reflected into HTML/JavaScript contexts at the identified endpoints.

Recommended fix High confidence

ChurchCRM 7.4.0

  1. 1. Back up your current ChurchCRM installation and database
  2. 2. Download ChurchCRM version 7.4.0 or later from the official repository (github.com/ChurchCRM/CRM)
  3. 3. Extract the new version to your web server directory
  4. 4. Run any database migration scripts if included in the release
  5. 5. Verify the upgrade was successful by accessing the application
  6. 6. Test the previously vulnerable endpoints (/FamilyCustomFieldsEditor.php, /PaddleNumList.php, /admin/system/church-info) to confirm the XSS vulnerability is resolved
