DescriptionNVD

The 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.

AnalysisAI

Insecure Direct Object Reference in WCFM Frontend Manager for WooCommerce (versions ≤6.7.25) allows authenticated vendors to manipulate arbitrary orders and delete any WordPress posts, products, or pages beyond their ownership scope. Exploitation requires only vendor-level credentials (PR:L) with no user interaction, enabling privilege escalation through unauthorized access to store-wide content. …

RemediationAI

Within 24 hours: Identify all WordPress instances running WCFM Frontend Manager ≤6.7.25 and document current vendor user accounts with active credentials; restrict vendor role permissions to read-only where possible pending patch availability. Within 7 days: Contact WCFM vendor for patch timeline and escalation; implement additional access controls or disable the plugin on non-critical environments if no patch is forthcoming. …
