AI Analysis
Technical Summary
CVE-2026-16746 is an authorization bypass vulnerability in the MultiVendorX WordPress plugin prior to version 5.0.11. The issue is due to the lack of verification that the requested store in a REST API endpoint belongs to the authenticated user. This allows vendor-level users to read sensitive commission and financial data of other vendors, violating data access controls. The vulnerability is categorized under CWE-639 (Authorization Bypass Through User-Controlled Key). No CVSS score or patch information is currently available.
Potential Impact
Unauthorized access to other vendors' commission and financial data can lead to data leakage and potential privacy violations within the MultiVendorX plugin environment. This compromises the confidentiality of sensitive financial information among vendors using the plugin.
