The Royal MCP WordPress plugin before 1.4.26 does not perform capability checks on the majority of its MCP tools after token authentication, allowing authenticated users with a low-privileged role such as Subscriber to read private content, enumerate all users and their roles, and create, modify, or delete content owned by other users.
AI Analysis
Technical Summary
CVE-2026-10750 describes a missing authorization vulnerability in the Royal MCP WordPress plugin prior to version 1.4.26. After token authentication, the plugin fails to enforce capability checks on most MCP tools, enabling low-privileged authenticated users to perform unauthorized actions including reading private content, enumerating users and roles, and manipulating content owned by others. This represents a significant privilege escalation risk within the affected plugin.
Potential Impact
Exploitation of this vulnerability allows low-privileged authenticated users (e.g., Subscribers) to access sensitive private content, gain visibility into all users and their roles, and create, modify, or delete content owned by other users. This compromises confidentiality and integrity of site content and user data. The vulnerability does not impact availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a patch is available, restrict plugin usage to trusted users and consider disabling the plugin if possible to prevent exploitation.
