Technical view
The issue is CWE-639, Authorization Bypass Through User-Controlled Key, in Extensions For CF7 through version 3.4.0. CVSS 3.1 is 5.3: network exploitable, low complexity, no privileges, no user interaction, with low confidentiality impact only. Public sources do not provide endpoint-level details or a named fixed version.
Likely exposure
Internet-facing WordPress sites using HT Plugins Extensions For CF7 version 3.4.0 or earlier are the likely exposure group. Sites not using this plugin are not indicated as affected.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. The CVSS vector indicates exploitation is remotely reachable without authentication, but public evidence here does not include exploit availability or technical attack details.
Researcher notes
Public data is sparse. The CVE and Patchstack entry identify an IDOR/access-control flaw, but do not provide technical root cause, affected endpoints, exploit status, or fixed-version details in the supplied bundle. Avoid assuming broader impact than low confidentiality exposure.
Mitigation direction
- Inventory WordPress sites for the Extensions For CF7 plugin.
- Identify installations running version 3.4.0 or earlier.
- Check HT Plugins, WordPress plugin, or Patchstack guidance for a fixed version.
- Update the plugin if an official fixed release is available.
- Disable or remove the plugin where it is not required.
Validation and detection
- Confirm the plugin slug is extensions-for-cf7.
- Record installed plugin versions across WordPress environments.
- Flag versions 3.4.0 or earlier for remediation review.
- Review access logs for unusual unauthenticated requests to plugin-related functionality.
- Recheck CVE and Patchstack entries for updated fix information.
