Security Findings (20)

• HighExcessive Permission Surface ×6

  • brave_web_search:tool declares network permission
  • brave_local_search:tool declares network permission
  • brave_video_search:tool declares network permission
  • brave_image_search:tool declares network permission
  • brave_news_search:tool declares network permission
  • brave_summarizer: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 ×3

  • brave_local_search:tool declares db permission
  • brave_video_search:tool declares db permission
  • brave_news_search:tool declares db 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 ×5

  • brave_web_search:tool declares http permission
  • brave_web_search:input schema exposes 15 properties (threshold: 10)
  • brave_local_search:tool declares http permission
  • brave_local_search:input schema exposes 15 properties (threshold: 10)
  • brave_news_search:input schema exposes 11 properties (threshold: 10)

  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 ×6

  • brave_web_search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • brave_local_search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • brave_video_search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • brave_image_search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • brave_news_search:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • brave_summarizer: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.
