Security readout for executives and security teams
Plain-English summary
CVE-2022-38067 affects the Totalsoft Event Calendar – Calendar WordPress plugin through version 1.4.6. An unauthenticated visitor may be able to delete calendar events, causing business disruption or loss of public event information without needing a WordPress account.
Executive priority
Prioritize remediation for public sites where calendar events support customer operations, registrations, or communications. This is not a data-theft issue based on current sources, but unauthorized deletion can disrupt business-facing content.
Technical view
The issue is an unauthenticated event deletion vulnerability in a WordPress plugin. CVSS 3.1 is 6.5 with network access, low complexity, no privileges, and no user interaction. The stated impact is integrity and availability; confidentiality impact is not indicated.
Likely exposure
Public WordPress sites using Totalsoft Event Calendar – Calendar plugin version 1.4.6 or earlier are the relevant exposure group.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. Because the flaw is unauthenticated and network-reachable, exposed public sites should still treat it as operationally relevant.
Researcher notes
Evidence is limited to the CVE record, Patchstack entry, and WordPress plugin page. The bundle does not provide exploit details, active exploitation evidence, or a named fixed version. CWE-264 is broad, so classify root cause cautiously.
Mitigation direction
- Identify all WordPress sites using the affected plugin.
- Check vendor, WordPress.org, or Patchstack guidance for a fixed release.
- Update the plugin if a supported fixed version is available.
- Disable or remove the plugin if no safe version is confirmed.
- Restore missing calendar data from backups if deletion occurred.
Validation and detection
- Inventory installed plugin names and versions across WordPress sites.
- Confirm whether any site runs Calendar plugin version 1.4.6 or earlier.
- Review calendar content for unexpected deleted or missing events.
- Review WordPress and hosting logs for suspicious anonymous activity.
- Document remediation status for each affected site.
