      <title>CVE-2026-77518 — MaxKB: Known MCP tool IDs expose owner Tool.code and can be referenced by attacker workflows</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-77518</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; 1Panel-dev MaxKB&lt;/p&gt;
&lt;p&gt;MaxKB is an open-source AI assistant for enterprise. In 2.10.2-lts and earlier, a normal workspace user who knows another user&amp;#39;s active MCP tool_id in the same workspace can retrieve the hidden tool through the tool-detail route because it does not apply the per-resource authorization used by the list route. The response includes Tool.code, which may contain MCP server configuration and headers, and an attacker who can create or edit an attacker-owned workflow can place the same foreign mcp_tool_id in a workflow mcp-node so workflow debug uses the owner&amp;#39;s MCP configuration without verifying permission to use that tool. No fixed version is available as of this review.&lt;/p&gt;</description>
