Privilege escalation via Insecure Direct Object Reference in the WCFM Membership (WooCommerce Memberships for Multivendor Marketplace) WordPress plugin versions up to and including 2.11.10 lets authenticated users holding at least vendor-level access manipulate the 'wcfmvm_membership_change' AJAX action to reassign any user's account to the 'wcfm_vendor' role by altering their membership plan. Because the action never checks whether the caller is authorized to modify the targeted user, a low-privileged marketplace vendor can tamper with arbitrary accounts. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the high CVSS of 8.1 and network-reachable authenticated vector make it a meaningful multivendor-store risk.
Authenticated vendors with low-level privileges can delete arbitrary WordPress users, including site administrators, via Insecure Direct Object Reference in WCFM - Frontend Manager for WooCommerce plugin versions up to 6.7.25. The vulnerability resides in the 'wcfm_delete_wcfm_customer' function which fails to validate user-controlled 'customerid' parameters, allowing privilege escalation through unauthorized user deletion. Patch available in version 6.7.26 per Trac changeset 3483695. No public exploit code or active exploitation confirmed at time of analysis, though CVSS 8.1 (High) reflects significant real-world impact if exploited by malicious vendors on WooCommerce marketplaces.
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. EPSS data not available; no public exploit identified at time of analysis, though the vulnerability's straightforward IDOR nature increases weaponization risk once details are public.
Unauthorized cross-vendor manipulation in WCFM - Frontend Manager for WooCommerce (all versions ≤ 6.7.27) allows authenticated subscriber-level users to archive competitor vendors' product listings, toggle featured status on arbitrary listings, mark WooCommerce orders as completed, and permanently delete enquiries and bulk messages belonging to other vendors within the same marketplace. Multiple AJAX handlers in class-wcfm-ajax.php, class-wcfm-enquiry.php, and class-wcfm-notification.php accept user-controlled object IDs without verifying ownership - a textbook CWE-639 IDOR pattern enabling horizontal privilege escalation across vendor accounts. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Stored XSS in WCFM Marketplace - Multivendor Marketplace for WooCommerce (all versions ≤ 3.7.3) permits authenticated attackers holding a Vendor-level account to plant persistent JavaScript payloads inside WordPress media attachment titles, targeting any privileged user who subsequently loads the media management dashboard. The injection path is notable for its stealth: the attacker uploads a media file with a crafted post_title via the standard WordPress REST API (/wp-json/wp/v2/media), bypassing any AJAX-based access controls, because the unescaped title is later serialized into DataTables JSON and written directly to the DOM via innerHTML on the admin media interface. No public exploit code is identified and the vulnerability has no CISA KEV listing at time of analysis, but the low privilege barrier - any marketplace vendor account - meaningfully elevates real-world risk in multi-vendor deployments with untrusted sellers.
Authorization bypass in WCFM - Frontend Manager for WooCommerce (all versions through 6.7.27) allows unauthenticated network attackers to inject arbitrary content into store inquiry replies, overwrite inquiry records in the wp_wcfm_enquiries database table, and trigger unsolicited notification emails to customers and vendors. The root cause is a missing authentication gate in the wcfm-my-account-enquiry-manage controller branch - unlike its sibling branches, it performs neither is_user_logged_in() nor current_user_can() checks. The nonce that serves as the sole barrier is embedded into every public page load without any login requirement, rendering it ineffective as an access control. No public exploit code and no CISA KEV listing identified at time of analysis.
