CVE-2026-39333
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 · uneditedChurchCRM is an open-source church management system. Prior to 7.1.0, he FindFundRaiser.php endpoint reflects user-supplied input (DateStart and DateEnd) into HTML input field attributes without proper output encoding for the HTML attribute context. An authenticated attacker can craft a malicious URL that executes arbitrary JavaScript when visited by another authenticated user. This constitutes a reflected XSS vulnerability. This vulnerability is fixed in 7.1.0.
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 confidenceChurchCRM versions prior to 7.1.0 contain a reflected XSS vulnerability in the FindFundRaiser.php endpoint. The DateStart and DateEnd parameters are reflected into HTML input field attributes without proper output encoding for the HTML attribute context, allowing authenticated attackers to inject arbitrary JavaScript via crafted URLs.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm ChurchCRM installationLocate the ChurchCRM application directory or check your web server for the ChurchCRM application filesAffected if ChurchCRM is installed on the server
-
Identify installed ChurchCRM versionCheck the version number of your ChurchCRM installation - typically found in the application header, footer, or in a version file within the installation directoryAffected if The installed version is anything prior to 7.1.0 (e.g., 7.0.x, older releases)
-
Locate FindFundRaiser.php endpointSearch for the FindFundRaiser.php file within the ChurchCRM web directoryAffected if The file exists and is accessible via the web server
-
Verify parameter reflection in HTML attributesAccess the FindFundRaiser.php endpoint with test values in the DateStart and DateEnd parameters, then view the page source to inspect how these values are rendered in HTML input field attributesAffected if The DateStart or DateEnd values appear unencoded in HTML attribute context (e.g., within value="" attributes)
-
Confirm authentication requirementsAttempt to access the FindFundRaiser.php endpoint to determine if authentication is requiredAffected if The endpoint is accessible to authenticated users only, meaning an attacker needs valid credentials to exploit the XSS
Your environment is affected if ChurchCRM versions prior to 7.1.0 are installed and the FindFundRaiser.php endpoint with unencoded DateStart/DateEnd parameters in HTML attributes is accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.1.0
Upgrade to ChurchCRM version 7.1.0 or later, which implements proper output encoding for the DateStart and DateEnd parameters in HTML attribute context.
ChurchCRM 7.1.0
- Verify current ChurchCRM version by checking the admin dashboard or system information page
- Backup the current ChurchCRM database and files before upgrading
- Download ChurchCRM version 7.1.0 from the official GitHub releases page (github.com/ChurchCRM/CRM)
- Extract the new version files to replace the existing installation
- Run any database migration scripts included in the 7.1.0 release
- Verify the upgrade was successful by logging into the admin panel
- Confirm the FindFundRaiser.php page now properly encodes DateStart and DateEnd parameters in HTML attribute context
