Miggo AIRoot Cause Analysis

The vulnerability stems from two key elements: 1) The install binary's SUID configuration allowing root execution, and 2) The control flow that executes an external binary ('calico -v') without proper validation. The main install process in install.go was vulnerable because it created directories as root and executed untrusted binaries. The fixes in PR#8517 replaced binary execution with content verification, confirming these functions were problematic. The 'copyBinary' function's role in setting permissions and handling binaries contributed to the insecure configuration.
