Security Findings (15)

• HighInsecure Secret Handling

  aws___get_regional_availability:input parameter "next_token" appears to accept a secret or credential

  Rule: AS-010Fix: 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.
• HighExcessive Permission Surface ×3

  • aws___read_documentation:tool declares network permission
  • aws___recommend:tool declares network permission
  • aws___search_documentation:tool declares network permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• MediumExcessive Permission Surface ×4

  • aws___get_regional_availability:tool declares db permission
  • aws___search_documentation:tool declares fs permission
  • aws___search_documentation:tool declares db permission
  • aws___search_documentation:tool declares env permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowExcessive Permission Surface ×2

  • aws___get_regional_availability:tool declares http permission
  • aws___list_regions:tool declares http permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowDoS Resilience — Missing Rate Limit / Timeout ×5

  • aws___get_regional_availability:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • aws___list_regions:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • aws___read_documentation:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • aws___recommend:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • aws___search_documentation:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

  Rule: AS-011Fix: 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.
