Security Findings (104)

• HighAS-002

  ⚠️Excessive Permissions ×5

  tool declares exec permission

  get_effective_permissionscreate_job

  tool declares network permission

  get_cluster_infocreate_network_policylist_flux_sources

  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-003

  🔀Scope Mismatch

  get_effective_permissions:tool name "get_effective_permissions" implies read-only operation but declares exec permission

  Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

• HighAS-010

  🔑Insecure Secret Handling ×2

  input parameter "secretName" appears to accept a secret or credential

  create_secretupdate_secret

  Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

• MediumAS-002

  ⚠️Excessive Permissions ×14

  tool declares fs permission

  create_jobcreate_configmapupdate_configmapcreate_secretupdate_secretcreate_deploymentdelete_deploymentcreate_namespacedelete_namespacecreate_horizontal_pod_autoscalercreate_serviceupdate_ingresscreate_network_policyremove_taint

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

• LowAS-002

  ⚠️Excessive Permissions

  restart_pod:tool declares http 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.

• LowAS-011

  ℹ️Missing Rate-Limit / Timeout ×6

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

  restart_podget_effective_permissionsget_cluster_infocreate_jobcreate_network_policylist_flux_sources

  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.

• InfoAS-014

  ℹ️Dependency Inventory Unavailable ×75

  Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.
