Affected versions of this package are vulnerable to Missing Authorization via the MCP loopback component, which fails to enforce the sandbox.tools.deny policy for sandboxed coding-agent sessions. An attacker operating within a sandboxed session can list and invoke tools that the operator explicitly denied, gaining access to data or actions intended to be excluded from the sandbox. Practical impact depends on the capabilities granted to the denied tools.
Note: This is only exploitable when MCP loopback is enabled for a sandboxed coding-agent session.
