CVE-2025-4101 in MultiVendorX Plugin
Summary
by MITRE • 05/17/2025
The MultiVendorX – WooCommerce Multivendor Marketplace Solutions plugin for WordPress is vulnerable to unauthorized loss of data due to a misconfigured capability check on the 'delete_fpm_product' function in all versions up to, and including, 4.2.22. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary posts, pages, attachments, and products. The vulnerability was partially patched in version 4.2.22.

The vulnerability identified as CVE-2025-4101 affects the MultiVendorX plugin for WordPress, specifically targeting the WooCommerce multivendor marketplace solution. This security flaw resides in the capability validation mechanism within the plugin's codebase, where the 'delete_fpm_product' function fails to properly verify user permissions before executing deletion operations. The issue represents a critical authorization bypass that allows authenticated users with Contributor-level privileges or higher to exploit the system and remove arbitrary content including posts, pages, attachments, and products from the WordPress installation. The vulnerability exists across all plugin versions up to and including 4.2.22, indicating a prolonged period during which the system remained exposed to potential exploitation.
The technical implementation of this vulnerability stems from improper capability checks within the plugin's core functionality. When an authenticated user attempts to delete content through the 'delete_fpm_product' function, the system should verify that the user possesses the appropriate administrative permissions before proceeding with the deletion. However, the current implementation fails to enforce these checks adequately, allowing users with Contributor-level access to bypass normal security boundaries. This misconfiguration creates an unauthorized data loss scenario where malicious actors can manipulate the system to remove content they should not have access to, potentially causing significant operational disruption and data integrity issues for marketplace administrators.
The operational impact of this vulnerability extends beyond simple data loss, as it compromises the fundamental security model of the WordPress platform. Contributors and other authenticated users with elevated privileges can now perform destructive actions that should be restricted to administrators or specific roles with explicit deletion permissions. This creates a cascading effect where the integrity of the marketplace's content management system is undermined, potentially leading to loss of product listings, customer data, and other critical business information. The vulnerability also undermines trust in the platform's security measures and could result in reputational damage for businesses relying on the affected plugin for their online marketplace operations.
The partial patch implemented in version 4.2.22 addresses some aspects of the vulnerability but does not fully resolve the underlying capability check issues. This incomplete remediation suggests that while the immediate exploitation vector has been partially closed, the root cause of the authorization flaw remains present in the system. Organizations using the MultiVendorX plugin should understand that merely updating to version 4.2.22 may not provide complete protection against this vulnerability. Security professionals should conduct thorough assessments of their WordPress installations to ensure that all instances of the plugin have been properly updated and that additional security measures have been implemented to protect against similar authorization bypass scenarios. The vulnerability aligns with CWE-284, which describes improper access control, and represents a clear violation of the principle of least privilege in security architecture. Organizations should also consider the ATT&CK framework's privilege escalation techniques, as this vulnerability enables attackers to move laterally within the system by leveraging their existing authenticated access to perform unauthorized deletions.
