CVE-2021-24199
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 allows a low privilege authenticated user to perform Boolean-based blind SQL Injection in the table list page on the endpoint /wp-admin/admin-ajax.php?action=get_wdtable&table_id=1, on the 'start' HTTP POST parameter. This allows an attacker to access all the data in the database and obtain access to the WordPress application.
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 contains a Boolean-based blind SQL Injection vulnerability in the admin-ajax.php endpoint. The vulnerability exists in the 'start' POST parameter when accessing /wp-admin/admin-ajax.php?action=get_wdtable&table_id=1, allowing authenticated users with low privileges to inject arbitrary SQL queries and exfiltrate database contents.

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.
-
Identify wpDataTables plugin installationCheck the WordPress plugins directory or inspect the plugin files. Look for wpdatatables folder in /wp-content/plugins/ and locate the main plugin file to read the version metadata.Affected if wpDataTables plugin is installed on the WordPress site
-
Determine installed wpDataTables versionOpen the main plugin file (typically wpdatatables.php or similar) and locate the version comment header, or check the plugin metadata via WordPress admin plugins page.Affected if The installed version is less than 3.4.2 (e.g., 3.4.1, 3.4.0, earlier versions)
-
Verify admin-ajax.php endpoint accessibilityCheck if the /wp-admin/admin-ajax.php endpoint is accessible on the WordPress site. This is typically accessible without authentication for logged-in users.Affected if The admin-ajax.php endpoint is reachable and responds to requests
-
Confirm user role exposureDetermine if low-privilege user accounts (subscriber, contributor, or custom low-privilege roles) can access the affected endpoint via the 'action=get_wdtable' parameter.Affected if Authenticated users with low privileges can access the vulnerable endpoint with the 'start' POST parameter
A site is affected if wpDataTables plugin version is below 3.4.2 AND the site has authenticated users who can access the admin-ajax.php endpoint with the get_wdtable action.

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
