CVE-2021-24197
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 · uneditedThe wpDataTables – Tables & Table Charts premium WordPress plugin before 3.4.2 has Improper Access Control. A low privilege authenticated user that visits the page where the table is published can tamper the parameters to access the data of another user that are present in the same table by taking over the user permissions on the table through formdata[wdt_ID] parameter. By exploiting this issue an attacker is able to access and manage the data of all users in the same table.
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 confidenceThe wpDataTables premium WordPress plugin before version 3.4.2 has an improper access control vulnerability where a low-privilege authenticated user can access data belonging to other users in the same table. The vulnerability stems from trusting the client-supplied formdata[wdt_ID] parameter without proper server-side validation of user permissions, allowing privilege escalation through parameter tampering.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify wpDataTables plugin is installedLog into WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'wpDataTables' or 'wpDataTables Premium' in the list of active plugins.Affected if The plugin is present and active in the WordPress installation
-
Check installed wpDataTables versionIn WordPress admin, go to Plugins > Installed Plugins. Find wpDataTables and locate the version number displayed under the plugin name. Alternatively, check the plugin's main PHP file header for the Version constant.Affected if Version is lower than 3.4.2 (e.g., 3.4.1, 3.4.0, 3.3.x, etc.)
-
Confirm table data functionality is accessible to low-privilege usersReview WordPress user roles and capabilities. Check if any user role other than Administrator has access to wpDataTables functionality. Test by logging in as a low-privilege user (e.g., Editor, Author, Subscriber) and attempt to access a wpDataTable.Affected if Low-privilege users (Subscriber, Contributor, Author, or Editor roles) have access to view table data
-
Inspect for wdt_ID parameter handlingUse browser developer tools or a proxy (like Burp Suite) to intercept requests when a user accesses a wpDataTable. Look for requests containing a 'wdt_ID' or 'formdata[wdt_ID]' parameter in the request body or URL.Affected if The application accepts and processes wdt_ID parameters from client-side requests without visible server-side permission checks
A user is affected if wpDataTables version is below 3.4.2 AND low-privilege authenticated users can access table data through the wdt_ID parameter without proper ownership verification.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data3.4.2
Upgrade to wpDataTables version 3.4.2 or later which contains proper access control checks. Until patched, limit table access to trusted users only.
