CVE-2026-56048
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 · uneditedUnauthenticated Insecure Direct Object References (IDOR) in Payment Gateway Based Fees and Discounts for WooCommerce <= 3.0.0 versions.
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 confidenceUnauthenticated IDOR vulnerability in the Payment Gateway Based Fees and Discounts for WooCommerce plugin allows remote attackers to access or modify payment fee/discount settings without authentication by manipulating object references in requests.

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.
-
Verify the plugin is installedCheck if the 'payment-gateway-based-fees-and-discounts-for-woocommerce' directory exists in wp-content/plugins/ on your WordPress server, or query the WordPress plugins API.Affected if Plugin directory or entry not found means not affected.
-
Identify the installed plugin versionOpen the main plugin file (e.g., payment-gateway-based-fees-and-discounts-for-woocommerce.php) and locate the 'Version' header in the plugin comment block, or check a dedicated version file if one exists.Affected if Version is lower than 3.0.1 indicates potentially affected.
-
Confirm WooCommerce is activeIn WordPress admin, go to Plugins > Active Plugins and verify WooCommerce is enabled, or query the active_plugins option in the wp_options table.Affected if Plugin cannot function without WooCommerce; if WooCommerce is not active, the attack surface may not apply.
-
Check for payment fee or discount configurationsIn WooCommerce > Settings > Fees and Discounts (or similar plugin settings page), verify if any payment gateway-based fees or discounts are configured and enabled.Affected if If no fee/discount rules are defined, the specific vulnerable endpoint may not be exploitable, but the IDOR flaw still exists in the code.
-
Inspect accessible AJAX or REST endpointsReview the plugin's PHP files for action hooks handling fee/discount updates (e.g., wp_ajax_ or wp_ajax_nopriv_ hooks) and check if they validate user capabilities or nonce tokens before processing object reference modifications.Affected if Endpoints accessible to unauthenticated users without proper authorization checks indicate the vulnerability is present.
You are affected if the plugin is installed with a version below 3.0.1 and WooCommerce is active, regardless of whether fee/discount rules are configured, since the unauthenticated IDOR vulnerability exists in the plugin code itself.
Generated from the published advisory. Verify against your own configuration.
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 version 3.0.1 or later. If no patched version is available, restrict access to the affected endpoints via web server configuration or temporarily disable the plugin.
