Risk Summary

Needs Approval

Excessive Permissions plus Supply Chain CVEs raises enough risk that this tool should not be auto-trusted.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (3)

  • HighAS-002

    ⚠️Excessive Permissions

    get_transcript:tool declares network permission

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • HighAS-004

    📦Supply Chain CVEs (OSV)

    get_transcript:GO-2026-5024 in golang.org/x/[email protected]: Invoking integer overflow in NewNTUnicodeString in golang.org/x/sys/windows (upgrade to 0.44.0)

    Fix: Upgrade or replace the vulnerable dependency. Pin all dependency versions and enable automated CVE scanning (Dependabot or OSV Scanner).

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout

    get_transcript:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.
