CVE-2026-4896
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 WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.25 via multiple AJAX actions including `wcfm_modify_order_status`, `delete_wcfm_article`, `delete_wcfm_product`, and the article management controller due to missing validation on user-supplied object IDs. This makes it possible for authenticated attackers, with Vendor-level access and above, to modify the status of any order, delete or modify any post/product/page, regardless of ownership.
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 WCFM Frontend Manager plugin for WooCommerce is vulnerable to Insecure Direct Object Reference (IDOR) in all versions up to 6.7.25. Multiple AJAX endpoints including wcfm_modify_order_status, delete_wcfm_article, delete_wcfm_product, and the article management controller fail to validate that the user has permission to access or modify the specific object IDs they supply. This allows authenticated Vendor-level users to modify any order status and delete/create/modify any post, product, or page on the WordPress site, regardless of ownership.

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 WCFM Frontend Manager is installedCheck your WordPress plugins directory for the WCFM Frontend Manager plugin and note its version number. In WordPress admin, go to Plugins > Installed Plugins and locate WCFM. The version is listed under the plugin name.Affected if The plugin is installed and active.
-
Compare installed version to any known fixed versionSince no specific version range is provided, check the official WCFM plugin changelog or WordPress repository for any mention of CVE-2026-4896 fixes. If the vendor has released a security update, compare your installed version to that release.Affected if Your version is older than the fixed version (once released) or no fix is available yet.
-
Confirm the vulnerable AJAX endpoints existIn the plugin source code, locate the registered AJAX handlers. Search for: wcfm_modify_order_status, delete_wcfm_article, and delete_wcfm_product. These should be registered via add_action('wp_ajax_wcfm_...').Affected if These AJAX action handlers exist in the plugin code without authorization checks.
-
Inspect the AJAX handler functions for ownership verificationExamine the PHP functions handling these AJAX requests (typically in includes/ajax.php or similar). Look for missing checks like get_current_user_id() comparison against the object author/owner, or missing capability checks (current_user_can).Affected if The handlers accept object IDs without verifying the current user owns or has permission to modify that specific object.
-
Check for Vendor role exposureReview the WordPress user roles on your site. Determine if the WCFM Vendor role is active and what capabilities it has. IDOR exploitation requires an attacker to have at least Vendor-level access.Affected if WCFM Vendor role exists and is assignable to users, enabling authenticated exploitation.
Your environment is affected if WCFM Frontend Manager is installed with the vulnerable AJAX endpoints exposed and no ownership validation exists in the handlers, especially if Vendor-level users exist on the site.
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.
dbcve · scopedUpgrade to version 6.7.26 or later which contains proper authorization validation. Additionally, implement object-level authorization checks on all AJAX endpoints to verify user ownership or appropriate permissions before allowing object manipulation.
Upgrade to WCFM – Frontend Manager for WooCommerce version 6.7.26 or later
- Navigate to the WordPress admin dashboard
- Go to Plugins > Installed Plugins
- Locate 'WCFM – Frontend Manager for WooCommerce'
- Check if the current version is 6.7.25 or earlier
- If vulnerable, click 'Update Now' to upgrade to the latest version
- Alternatively, download the updated plugin from wordpress.org/plugins/wc-frontend-manager/ and upload manually
- After update, verify the version number reflects the fix
