CVE-2026-58168: Missing Authorization in HKUDS DeepTutor
DeepTutor before version 1.4.10 contains an authorization bypass vulnerability that allows low-privilege users to invoke unrestricted MCP tools due to the allowed_mcp_tools function returning None instead of a denied result when mcp_tools is omitted from a user's grant in deeptutor/multi_user/tool_access.py. Attackers or prompt-injected content acting within a user session can enumerate and invoke any configured MCP tool, including filesystem, shell, and browser servers, gaining unauthorized access to sensitive deployment resources.
AI Analysis
Technical Summary
CVE-2026-58168 is an authorization bypass vulnerability in HKUDS DeepTutor before version 1.4.10. The flaw arises from the allowed_mcp_tools function in deeptutor/multi_user/tool_access.py returning None rather than a denial when a user's grant omits mcp_tools. This allows low-privilege users or prompt-injected content within a user session to enumerate and invoke any configured MCP tool, including those providing filesystem, shell, and browser server access, leading to unauthorized access to sensitive resources.
Potential Impact
Successful exploitation can lead to unauthorized access to sensitive deployment resources with high confidentiality, integrity, and availability impact. Attackers can invoke powerful MCP tools without proper authorization, potentially compromising the system's security and control.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch link is provided, users should monitor HKUDS advisories for updates. Until a fix is available, restrict access to DeepTutor installations to trusted users and environments to minimize risk.
