CVE-2026-1870: Thim Kit for Elementor <= 1.3.7 - Missing Authorization to Unauthenticated Private Course Disclosure

The Thim Kit for Elementor – Pre-built Templates & Widgets for Elementor plugin for WordPress is vulnerable to unauthorized access of data due to a missing validation checks on the 'thim-ekit/archive-course/get-courses' REST endpoint callback function in all versions up to, and including, 1.3.7. This makes it possible for unauthenticated attackers to disclose private or draft LearnPress course content by supplying post_status in the params_url payload.

Security readout for executives and security teams

Plain-English summary

This WordPress plugin flaw can let unauthenticated visitors view LearnPress course content that was intended to stay private or in draft. It does not allow code execution or site takeover in the published assessment, but it can expose unpublished training material, paid course previews, or internal content.

Executive priority

Treat as a moderate-priority web content exposure issue. Prioritize sites that host paid, confidential, or unreleased course material. It should be remediated during the next regular WordPress maintenance window, faster for high-value course libraries.

Technical view

CVE-2026-1870 is a missing authorization issue in Thim Kit for Elementor up to and including 1.3.7. The REST endpoint callback for course archive retrieval lacks validation, allowing unauthenticated disclosure of private or draft LearnPress course content through request parameters. CVSS is 5.3, network exploitable, low confidentiality impact.

Likely exposure

Exposure is likely limited to WordPress sites using Thim Kit for Elementor versions through 1.3.7 with LearnPress course content marked private or draft. Publicly reachable WordPress REST interfaces increase practical exposure.

Exploitation context

The CVE record does not indicate active exploitation, and it is not listed as KEV. The issue requires no login and low complexity, but the documented impact is information disclosure only, not modification, denial of service, or remote code execution.

Researcher notes

Evidence identifies CWE-862 and affected versions through 1.3.7. The public bundle references a WordPress plugin changeset, but does not explicitly name a fixed version. Do not assume exploitation in the wild without additional evidence.

Mitigation direction

  • Identify WordPress sites running Thim Kit for Elementor.
  • Check whether installed versions are 1.3.7 or earlier.
  • Review vendor and WordPress plugin guidance for the fixed release.
  • Update the plugin if a vendor-supported fixed version is available.
  • Restrict access to sensitive draft or private course content where feasible.
  • Monitor for unusual REST requests to the affected course archive endpoint.

Validation and detection

  • Confirm whether Thim Kit for Elementor is installed.
  • Record the plugin version on each WordPress site.
  • Verify whether LearnPress private or draft courses exist.
  • Review web logs for unauthenticated access to the affected REST route.
  • Confirm remediation by rechecking plugin version and vendor release notes.

Missing Authorization

Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
