SEC600 / MCP-AUTOAPPROVE-GIT-BRANCH ​

SEC600 flags MCP configuration when autoApprove includes the exact tool token Bash(git branch:*).

Why It Matters ​

git branch mutates repository branch state. Auto-approving it removes review from shared branch-management authority.

Trigger Shape ​

  • the file is a detected MCP configuration surface
  • autoApprove is a string array
  • the array contains the exact item Bash(git branch:*)

How To Fix ​

Remove shared git branch auto-approval and keep branch mutation under explicit user review.
