Security readout for executives and security teams

Plain-English summary

Older WP Darko Responsive Tabs plugin versions can allow script-related HTML to be injected into tab content. For a business, this is mainly an integrity and availability risk: site content could be altered or disrupted. The provided sources do not show active exploitation.

Executive priority

Treat as a moderate-priority web-content integrity issue. Prioritize internet-facing WordPress sites and environments where non-administrators can edit content. Remediation should be routine but not deferred indefinitely.

Technical view

CVE-2023-45635 is a CWE-80 basic XSS or HTML content injection issue in the WordPress Responsive Tabs plugin before 4.0.6. The CVSS 3.1 score is 5.4 with network access, low complexity, low privileges required, no user interaction, and limited integrity and availability impact.

Likely exposure

Exposure is limited to WordPress sites running WP Darko Responsive Tabs below version 4.0.6. Sites not using this plugin, or already on 4.0.6 or later, are not indicated as affected in the supplied sources.

Exploitation context

The source bundle does not cite active exploitation, and CISA KEV status is false. The CVSS vector indicates exploitation requires some privileges but no user interaction, so risk is higher where many users can edit plugin-managed content.

Researcher notes

Available evidence identifies the vulnerable component, version boundary, CWE, and CVSS vector, but does not provide detailed exploit mechanics. Avoid assuming unauthenticated exploitability; the vector specifies PR:L.

Mitigation direction

  • Inventory WordPress sites for the Responsive Tabs plugin.
  • Upgrade Responsive Tabs to version 4.0.6 or later.
  • Restrict who can edit tab or plugin-managed content.
  • Review vendor and Patchstack guidance for any additional remediation.
  • Remove the plugin where it is unused or no longer needed.

Validation and detection

  • Check each site's installed Responsive Tabs version.
  • Flag any instance below version 4.0.6 as vulnerable.
  • Review plugin-managed tab content for unexpected script-related HTML.
  • Confirm only trusted users can modify affected content areas.
  • Record remediation status in the vulnerability tracker.
