Security readout for executives and security teams
Plain-English summary
This is a medium-severity CSRF issue in the WordPress My Calendar plugin. An attacker could trick an authenticated user into performing unintended plugin-related actions, potentially affecting site content or availability. The source bundle does not show active exploitation.
Executive priority
Treat as a normal-priority remediation item for WordPress estates using this plugin. It is not KEV-listed in the provided data, but it can affect integrity or availability if a privileged user is tricked.
Technical view
CVE-2022-47427 is a CWE-352 Cross-Site Request Forgery vulnerability affecting Joseph C Dolson My Calendar plugin versions <= 3.3.24.1. CVSS 3.1 is 5.4, with network attack vector, low complexity, no attacker privileges, required user interaction, and limited integrity and availability impact.
Likely exposure
Exposure is limited to WordPress sites with the My Calendar plugin installed at version 3.3.24.1 or earlier. Risk is higher where privileged WordPress users stay authenticated while browsing untrusted content.
Exploitation context
The CVSS vector requires user interaction and shows no confidentiality impact. The bundle marks KEV as false, and the cited sources do not provide evidence of known exploited status or public exploit maturity.
Researcher notes
The public data identifies the vulnerability class, affected plugin threshold, CVSS vector, and CWE. It does not provide exploit details, a specific fixed version, or confirmed in-the-wild exploitation. Avoid assuming broader WordPress impact beyond this plugin.
Mitigation direction
- Inventory WordPress sites for the My Calendar plugin.
- Upgrade the plugin following vendor or Patchstack guidance if a fixed release is available.
- Disable or remove the plugin where upgrade status cannot be confirmed.
- Limit privileged WordPress admin sessions to trusted workflows.
- Monitor vendor advisories for exact remediation guidance.
Validation and detection
- Confirm whether My Calendar is installed on each WordPress site.
- Verify no installed version is 3.3.24.1 or earlier.
- Review Patchstack or vendor guidance for fixed-version details.
- Test calendar functionality after update, disablement, or removal.
- Review admin activity for unexpected calendar-related changes.
