CVE-2026-1787: LearnPress Export Import <= 4.1.0 - Missing Authentication to Unauthenticated Migrated Course Deletion

The LearnPress Export Import – WordPress extension for LearnPress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'delete_migrated_data' function in all versions up to, and including, 4.1.0. This makes it possible for unauthenticated attackers to delete course that have been migrated from Tutor LMS. The Tutor LMS plugin must be installed and activated in order to exploit the vulnerability.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1787 affects the LearnPress Export Import WordPress extension. An unauthenticated attacker may delete courses migrated from Tutor LMS if Tutor LMS is also installed and active. The business impact is targeted data loss rather than server takeover. Urgency is moderate, especially for training, education, or commerce sites relying on migrated course content.

Executive priority

Treat as a moderate-priority data integrity issue. Prioritize affected education or training sites where course deletion would disrupt revenue, learning delivery, or customer trust. This is less urgent than remote code execution, but remediation should not wait on sites with active Tutor LMS migrations.

Technical view

The issue is a missing capability check, CWE-862, in the delete_migrated_data function in LearnPress Export Import up to and including 4.1.0. Wordfence rates it CVSS 4.8 with network access, no privileges, no user interaction, high attack complexity, low integrity impact, and low availability impact.

Likely exposure

Exposure appears limited to WordPress sites running LearnPress Export Import <= 4.1.0 with Tutor LMS installed and activated, and with courses migrated from Tutor LMS. Sites without Tutor LMS active or without migrated Tutor LMS course data are less likely to be practically affected based on the CVE description.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation is described as unauthenticated but high complexity, and it targets deletion of migrated course data rather than confidentiality or code execution.

Researcher notes

Evidence points to an unauthenticated missing authorization check in TutorMigrationController.php. The CVE states exploitation requires Tutor LMS to be installed and activated. The referenced WordPress Trac changeset is relevant for remediation review, but the provided bundle does not name a fixed release version.

Mitigation direction

  • Identify sites running LearnPress Export Import and Tutor LMS together.
  • Upgrade LearnPress Export Import beyond 4.1.0 if a vendor-fixed release is available.
  • Review the WordPress plugin changeset and vendor guidance before deploying changes.
  • Back up course data before updating or changing migration components.
  • Restrict unnecessary plugin exposure by disabling unused migration tooling.

Validation and detection

  • Inventory WordPress sites for LearnPress Export Import versions <= 4.1.0.
  • Check whether Tutor LMS is installed and activated.
  • Confirm whether Tutor LMS course data was migrated into LearnPress.
  • Review logs for unexpected migrated course deletion events.
  • Verify the installed plugin includes the authorization changes from the referenced changeset.
