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 · moderate confidenceA blind SQL injection vulnerability exists in the Product Filter by WBW WordPress plugin up to version 3.1.2. The vulnerability allows unauthenticated attackers to inject malicious SQL queries through insufficiently sanitized user input in the plugin's filter functionality. The 'blind' classification indicates the application does not return SQL errors directly, requiring attackers to infer results through behavioral differences.

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.
-
Locate the Product Filter by WBW plugin installationCheck the wp-content/plugins/ directory for a folder named 'product-filter-by-wbw' or similar variant. In WordPress admin, navigate to Plugins > Installed Plugins and look for 'Product Filter by WBW' or 'WBW Product Filter'.Affected if The plugin folder exists in wp-content/plugins/ or the plugin appears in the WordPress plugins list
-
Identify the installed plugin versionIn WordPress admin > Plugins > Installed Plugins, click on the plugin to view details and note the version number. Alternatively, open the main plugin PHP file (usually product-filter-by-wbw.php) and locate the 'Version' header in the plugin comment block.Affected if The version number is 3.1.2 or lower
-
Confirm the plugin is activeIn WordPress admin > Plugins, verify that Product Filter by WBW shows as 'Active' rather than 'Inactive' or 'Must Use'.Affected if The plugin is currently activated on the WordPress site
-
Determine if filter functionality is in useCheck if the product filter shortcode or block is embedded on any shop/archive pages. Look for shortcodes like [wbw_product_filter] or filter widgets in the Appearance > Widgets section. Visit the site's shop pages to see if filter controls are visible.Affected if Product filter controls appear on any public-facing pages, meaning the vulnerable endpoint is accessible to unauthenticated users
If Product Filter by WBW is installed, active, version 3.1.2 or lower, and the filter functionality is accessible on the site, the environment is likely affected by this blind SQL injection vulnerability.

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 Product Filter by WBW plugin to the latest patched version once released. Until a patch is available, consider disabling the plugin, implementing a WAF with SQL injection rules, or restricting access to the vulnerable endpoint.
