CVE-2026-11590
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 WP Support Plus Responsive Ticket System WordPress plugin through 9.1.2 does not sanitize user-supplied array keys before using them in a SQL statement, allowing unauthenticated users to perform SQL injection attacks.
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 WP Support Plus Responsive Ticket System WordPress plugin through version 9.1.2 fails to sanitize user-supplied array keys before using them in SQL queries, allowing unauthenticated attackers to inject malicious SQL code via the array key parameters.

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.
-
Confirm plugin installation statusIn WordPress admin dashboard, go to Plugins > Installed Plugins and look for 'WP Support Plus Responsive Ticket System' or check wp-content/plugins directory for wpsp-ticket-system folderAffected if Plugin is installed and active in WordPress
-
Check installed version numberIn WordPress admin under Plugins > Installed Plugins, find the plugin and view the version number; alternatively check version in plugin's main PHP file headerAffected if Version is 9.1.2 or lower (the flaw affects through version 9.1.2)
-
Identify exposed endpointsExamine plugin's AJAX handlers (usually in wp-admin/admin-ajax.php or frontendajax calls) and form submissions that handle ticket/array parameters; check plugin PHP files for $_POST or $_GET usage with array key access patternsAffected if The endpoint handling array parameters from user input is publicly accessible without authentication
-
Verify SQL query execution with array keysReview plugin source code for direct usage of array keys (e.g., $_POST['key'], $_REQUEST['key']) in $wpdb->prepare, $wpdb->query, or similar database functions without proper sanitization via intval, array_map, or key sanitization functionsAffected if Array parameters from user input are used directly in SQL queries without sanitization of array keys
If the plugin is installed, active, and at version 9.1.2 or below with user-controlled array parameters reaching unsanitized SQL queries, the environment is affected by this CVE.

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 dataUpdate the plugin to the latest patched version as soon as available. Until then, deploy a WAF rule to block SQL injection attempts targeting the affected parameters and consider temporarily disabling the plugin if immediate patching is not possible.
