CVE-2026-42289
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 7.3.2, UserEditor.php processes user account creation and permission updates entirely through $_POST parameters with no CSRF token validation. An unauthenticated attacker can craft a malicious HTML page that, when visited by an authenticated administrator, silently elevates any low-privilege user to full administrator or creates a new admin backdoor account without the victim's knowledge This vulnerability is fixed in 7.3.2.
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.

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.
-
Identify ChurchCRM installationLocate the ChurchCRM web application directory and check for the presence of UserEditor.php file within the src directory structure (commonly at /src/UserEditor.php or /modules/UserEditor.php)Affected if UserEditor.php file exists in the ChurchCRM installation
-
Determine installed ChurchCRM versionCheck the version.php file, composer.json, or version header in the application for the installed ChurchCRM version numberAffected if Installed version is below 7.3.2 (versions prior to the security patch)
-
Verify CSRF token validation exists in UserEditor.phpOpen UserEditor.php and search for CSRF token validation logic - look for functions like validateToken(), verifyCSRFToken(), or token checks using $_POST['csrf_token'] or $_SESSION['csrf_token']Affected if UserEditor.php contains no CSRF token validation code for $_POST parameters handling user creation or permission changes
-
Check for SameSite cookie configurationInspect the application cookie configuration or session settings for SameSite attribute; this is a secondary mitigation that should be present if CSRF tokens are not implementedAffected if SameSite cookie attributes are not configured and CSRF validation is missing
-
Audit admin accounts for unauthorized changesReview the user database table (typically persons or user tables) for any admin-level accounts created or modified around the time of potential exposure, or check user_permission tables for unexpected administrator role assignmentsAffected if Unexpected administrator accounts exist or user permissions were modified without documented admin action
The environment is affected if ChurchCRM is installed with a version below 7.3.2 AND UserEditor.php processes user operations without CSRF token validation.

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 · scopedUpgrade to ChurchCRM version 7.3.2 or later which implements CSRF token validation on all state-changing operations in UserEditor.php. As a temporary workaround, implement SameSite cookie attributes and manually add CSRF tokens to the user management forms.
7.3.2
- 1. Back up the current ChurchCRM database and all files
- 2. Download ChurchCRM version 7.3.2 from the official repository (github.com/ChurchCRM/CRM)
- 3. Review the official upgrade documentation at docs.churchcrm.io for version 7.3.2 specific upgrade instructions
- 4. Replace the existing application files with the new version 7.3.2 files, preserving any custom configuration
- 5. Run any database migration scripts included in the 7.3.2 release
- 6. Verify the upgrade by logging in and confirming UserEditor.php now includes CSRF token validation
- 7. Test that user creation and permission updates work correctly with the new CSRF protection
