Security readout for executives and security teams
Plain-English summary
This is a WordPress plugin access-control flaw affecting Connector to CiviCRM with CiviMcRestFace through version 1.0.10. An unauthenticated network attacker may perform actions that should require authorization, with limited integrity impact reported. No active exploitation is identified in the supplied sources.
Executive priority
Prioritize remediation for public WordPress sites that integrate with CiviCRM. This is a moderate business risk because it can affect data or workflow integrity, but the supplied sources do not support emergency active-exploitation claims.
Technical view
CVE-2025-31618 is CWE-862 Missing Authorization in connector-civicrm-mcrestface. CVSS 3.1 is 5.3: network reachable, low complexity, no privileges or user interaction, unchanged scope, no confidentiality or availability impact, and low integrity impact.
Likely exposure
Exposure is most likely on WordPress sites running the Connector to CiviCRM with CiviMcRestFace plugin, especially if publicly reachable and version 1.0.10 or earlier is installed.
Exploitation context
The source bundle does not show KEV listing, public exploitation, exploit code, or confirmed attacks. Treat exploitation status as unconfirmed, not actively exploited.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The CVE description states affected through <= 1.0.10, while the Patchstack URL text references 1.0.9; use vendor guidance to resolve version and fix details.
Mitigation direction
- Inventory WordPress sites for connector-civicrm-mcrestface installations.
- Check vendor or Patchstack guidance for a fixed version or official mitigation.
- Remove or disable the plugin where it is not required.
- Limit public access to affected connector functionality where operationally feasible.
- Review WordPress and CiviCRM authorization settings for least privilege.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the installed plugin version and compare against <= 1.0.10.
- Review vendor and Patchstack advisories for remediation status.
- Check logs for unexpected unauthenticated use of connector functionality.
- Verify CiviCRM role mappings and WordPress permissions are intentional.
