      <title>CVE-2026-58168 — DeepTutor &lt; 1.4.10 - Insecure Default Grants Unrestricted MCP Tool Access to Non-Admin Users</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-58168</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; HKUDS DeepTutor&lt;/p&gt;
&lt;p&gt;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&amp;#39;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.&lt;/p&gt;</description>
