Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.2.6.3 due to missing validation on a user controlled key when looking up order information. This makes it possible for authenticated attackers to obtain information on orders placed by other users and guests, which can be leveraged to sign up for paid courses that were purchased by guests. Emails of other users are also exposed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The LearnPress WordPress LMS plugin has an Insecure Direct Object Reference (IDOR) vulnerability in the order lookup functionality. Authenticated attackers can manipulate a user-controlled key parameter to access order information belonging to other users or guests, exposing sensitive data like email addresses and potentially allowing attackers to hijack paid course enrollments.

MitigationUpdate LearnPress to version 4.2.6.4 or later. In the meantime, implement proper authorization checks in the order lookup code to verify that the requesting user owns the order before returning any data, and validate that the order ID parameter cannot be manipulated to access other users' orders.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm LearnPress plugin is installed
    Log into WordPress admin and navigate to Plugins > Installed Plugins, or use wp-cli: wp plugin list --name=learnpress --status=active --format=table
    Affected if LearnPress is not listed as an installed and active plugin, then the site is not affected by this CVE.
  2. Check installed LearnPress version
    In WordPress admin, go to Plugins > Installed Plugins and find LearnPress to read the version number. Alternatively, check the main plugin file (learnpress.php) in wp-content/plugins/learnpress for the 'Version' header, or run: grep -i 'Version:' wp-content/plugins/learnpress/learnpress.php
    Affected if The installed version is lower than 4.2.6.4 (e.g., 4.2.6.3, 4.2.5.x, etc.), indicating the vulnerable version is in use.
  3. Verify order lookup feature is accessible
    Confirm the LearnPress order lookup page is publicly accessible by visiting a typical order lookup URL such as /lp-order-confirmation/ or /orders/ and checking if unauthenticated or authenticated users can submit an order lookup request.
    Affected if The order lookup functionality is active and accessible to users without proper authorization checks.
  4. Test for IDOR in order lookup
    Log in as a registered user, locate an existing order belonging to that user, then attempt to manipulate the order lookup request (e.g., change order ID or key parameter) to access a different user's order. Inspect the response for any order details belonging to another user, such as email addresses or course enrollment information.
    Affected if Manipulating the order ID or key parameter returns order data belonging to a different user or guest, confirming the IDOR vulnerability is present.

A site is affected if LearnPress version is below 4.2.6.4 AND the order lookup feature is accessible, allowing unauthorized access to other users' order information through parameter manipulation.

Upgrade available Upgrade to 4.2.6.4 or later
Fixed in 4.2.6.4
Interim mitigation

Update LearnPress to version 4.2.6.4 or later. In the meantime, implement proper authorization checks in the order lookup code to verify that the requesting user owns the order before returning any data, and validate that the order ID parameter cannot be manipulated to access other users' orders.

Recommended fix High confidence
