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 Master Slider Pro versionLocate the plugin files in wp-content/plugins/master-slider and check the main plugin file (e.g., masterslider.php) for the version header comment, or check the plugin admin dashboard under Plugins > Installed PluginsAffected if The installed version is 3.6.5 or any version lower than 3.6.5
-
Confirm plugin is activeCheck WordPress admin dashboard under Plugins > Installed Plugins to verify Master Slider Pro is activated, or query the wp_options table for option_name = 'active_plugins'Affected if The plugin is installed and active on the WordPress site
-
Identify SQL input pointsReview plugin source code in the includes or classes folder for direct usage of $_GET, $_POST, or $_REQUEST variables in SQL queries without prepare() or escaping functionsAffected if Custom code or third-party extensions pass unsanitized user input directly to SQL queries
-
Check slider public endpointsTest common Master Slider endpoints (e.g., /?masterslider&action=... or AJAX endpoints) by reviewing plugin routing code for parameters used in database queries without sanitizationAffected if Public-facing endpoints accept user input that flows directly into SQL queries
The environment is affected if Master Slider Pro version 3.6.5 or lower is installed and active, with unsanitized input parameters being used in SQL queries.

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 Master Slider Pro to the latest patched version. If no patch is available, implement parameterized queries (prepared statements) for all database interactions and apply proper input validation and escaping on user-supplied data.
