CVE-2026-96525: CWE-862 Missing Authorization in MCP Server for WordPress
CVE-2026-96525 is a missing authorization vulnerability in the MCP Server for WordPress plugin before version 1.8.2. It allows users with the Contributor role to create, update, and delete site-wide workflow configurations via REST routes without proper ownership or capability checks. This includes workflows created by administrators, potentially enabling unauthorized modification of critical site workflows.
AI Analysis
Technical Summary
The MCP Server for WordPress plugin versions prior to 1.8.2 do not enforce sufficient authorization checks on REST API endpoints responsible for creating, updating, and deleting workflow configurations. Users assigned the Contributor role, which normally has limited privileges, can exploit this flaw to modify or delete workflows across the site, including those established by administrators. This is classified as CWE-862: Missing Authorization.
Potential Impact
Users with the Contributor role can modify, delete, or create site-wide workflow configurations, including those created by administrators. This could lead to unauthorized changes in site behavior and workflow management, potentially disrupting site operations or enabling privilege escalation through workflow manipulation.
Mitigation Recommendations
Upgrade the MCP Server for WordPress plugin to version 1.8.2 or later, where proper authorization checks have been implemented. No other mitigation guidance is provided, and patch availability is confirmed by the fixed version.
