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 · uneditedMissing Authorization vulnerability in Jaap Jansma Connector to CiviCRM with CiviMcRestFace connector-civicrm-mcrestface allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Connector to CiviCRM with CiviMcRestFace: from n/a through <= 1.0.10.
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 · moderate confidenceMissing authorization vulnerability in the Connector to CiviCRM with CiviMcRestFace plugin allows attackers to exploit incorrectly configured access control security levels. This enables unauthorized access to functionality or data that should be restricted by proper ACL configuration.

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.
-
Verify the CiviMcRestFace plugin is installedCheck the WordPress plugin directory or CiviCRM extensions directory for the presence of the Connector to CiviCRM plugin with CiviMcRestFace component. Look for plugin files or extension directories containing 'civimcrestface' or similar naming.Affected if The plugin or extension is found in the system, indicating the vulnerable component is present.
-
Locate the plugin configuration fileFind the configuration or settings file for the CiviMcRestFace connector. Common paths may include WordPress wp-content/plugins directory, CiviCRM extensions folder, or custom configuration directories. Look for files named config, settings, or XML definitions related to the connector.Affected if Configuration files exist and are accessible, suggesting the plugin is actively configured.
-
Inspect ACL security level settingsOpen the plugin configuration and locate access control settings. Look for fields labeled 'security level', 'ACL', 'access control', 'permission level', or similar terms that control who can access the connector functionality. Examine the current value set for these security parameters.Affected if The security level is set to a permissive value (such as 'none', 'public', '0', or a setting that bypasses authentication) or is incorrectly configured to allow unrestricted access.
-
Test endpoint accessibility without authorizationIf possible, attempt to access the CiviMcRestFace API endpoints directly using a tool like curl or a browser request, without providing valid authentication credentials or API keys. Check if the endpoints return data or allow actions without requiring authorization headers or tokens.Affected if Requests to the connector endpoints succeed without authentication, confirming the missing authorization vulnerability.
-
Review audit logs for unauthorized access patternsCheck server access logs, CiviCRM logs, or application logs for repeated requests to the CiviMcRestFace endpoints from unknown or unauthenticated sources. Look for suspicious access patterns that indicate exploitation attempts.Affected if Logs show successful access to sensitive data or functionality by unauthenticated sources.
A user is affected if the CiviMcRestFace plugin is installed and the ACL security level is misconfigured to allow unauthenticated or unauthorized access to restricted endpoints.

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 · scopedImplement proper authorization checks and correct the access control security level configuration in the plugin; verify all endpoints enforce permission validation before granting access.
Latest version beyond 1.0.10 (vendor has not specified exact fixed release in available disclosure)
- 1. Identify the currently installed version of 'Connector to CiviCRM with CiviMcRestFace' in your WordPress environment
- 2. Navigate to the plugins/settings area where the connector is configured
- 3. Review and verify all access control settings and security levels within the CiviMcRestFace connector configuration
- 4. Check the official WordPress plugin repository or vendor documentation for the latest version
- 5. Backup your current website and database before performing any updates
- 6. Upgrade to the latest available version of the plugin that addresses this authorization vulnerability
- 7. After upgrading, verify that proper authorization checks are now enforced on all sensitive endpoints
