CVE-2025-49998
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 · uneditedMissing Authorization vulnerability in Wetail WooCommerce Fortnox Integration woocommerce-fortnox-integration allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WooCommerce Fortnox Integration: from n/a through <= 4.5.5.
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 confidenceThe WooCommerce Fortnox Integration plugin versions up to 4.5.5 contain a missing authorization vulnerability that allows attackers to exploit incorrectly configured access control security levels. This likely permits unauthenticated or insufficiently authorized users to access sensitive functionality intended for higher-privileged users, such as syncing order data with the Fortnox accounting system.

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 Fortnox Integration plugin is installedLocate the plugin directory in wp-content/plugins/ and check for the fortnox-integration folder, or query the WordPress plugins database table for the plugin nameAffected if The plugin is present in the WordPress installation
-
Determine the installed plugin versionOpen the main plugin file (typically fortnox-integration.php) and read the Version header comment, or query wp_options for the active_plugins optionAffected if The version number is 4.5.5 or lower (any version up to and including 4.5.5)
-
Identify exposed Fortnox sync endpointsExamine the plugin files for AJAX actions (add_action with wp_ajax_) or REST API routes (register_rest_route) that handle order synchronization, particularly those lacking capability checks like 'manage_woocommerce'Affected if The plugin exposes order sync endpoints accessible without capability verification
-
Test for missing authorization on sync functionalityReview plugin code for functions handling Fortnox order sync (search for fortnox_sync, update_order_to_fortnox, or similar) and verify if they include current_user_can() or permission callbacks before executing sensitive operationsAffected if Sync functions execute without verifying user permissions or roles first
The environment is affected if the WooCommerce Fortnox Integration plugin version 4.5.5 or lower is installed AND the order sync functionality is accessible without proper user capability checks

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 dataImplement proper authorization checks and role-based access control (RBAC) across all plugin endpoints and functions, ensuring that only users with appropriate permissions can execute sensitive operations.
