CVE-2026-57771
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 · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Milan Petrovic GD Rating System gd-rating-system allows Blind SQL Injection.This issue affects GD Rating System: from n/a through <= 3.7.
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 confidenceBlind SQL Injection vulnerability in GD Rating System plugin allows attackers to inject malicious SQL queries through unsanitized input parameters. The 'improper neutralization' indicates user-supplied data is being directly concatenated into SQL statements without proper escaping or use of parameterized queries.

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.
-
Check installed plugin versionAccess WordPress admin dashboard, navigate to Plugins > Installed Plugins, locate 'GD Rating System', and read the version number from the plugin metadata. Alternatively, check the plugin's main PHP file or readme.txt for the 'Version:' header.Affected if The installed version is 3.7 or any earlier version (e.g., 3.6, 3.5, etc.)
-
Identify plugin SQL query handlersLocate all PHP files within the GD Rating System plugin directory that contain SQL query construction (search for keywords like '$wpdb->prepare', 'mysql_query', 'mysqli_query', or direct string concatenation with SQL keywords such as 'SELECT', 'INSERT', 'UPDATE', 'DELETE').Affected if The plugin contains PHP files that construct SQL queries using unsafe methods.
-
Inspect parameter handling in SQL codeExamine the identified SQL query files for user-supplied input being passed directly into queries without using $wpdb->prepare() with proper placeholders (%s, %d), or without applying sanitization functions like esc_sql() or intval().Affected if User input parameters (from $_GET, $_POST, $_REQUEST) are used in SQL queries without parameterized preparation or sanitization.
-
Verify exposure of vulnerable endpointsDetermine if the plugin exposes functionality to unauthenticated or low-privilege users. Review AJAX handlers (wp_ajax_ hooks), shortcodes, or public-facing components that process user input and interact with the database.Affected if The plugin processes user input through SQL queries via publicly accessible endpoints without authentication or proper access controls.
You are affected if GD Rating System version 3.7 or earlier is installed and the plugin processes user input in SQL queries without parameterized preparation or sanitization.

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 dataReplace dynamic SQL construction with parameterized queries/prepared statements and implement strict input validation on all user-supplied parameters before database interaction.
