Miggo AIRoot Cause Analysis

The vulnerability stemmed from unsandboxed Groovy compilation in form validation endpoints. The commit diff shows the original validate() used GroovyShell directly (vulnerable), while the patched version uses GroovySandbox and ScriptApproval. The doCheckScriptContent method exposed this validation to HTTP endpoints without proper security checks (added RequirePOST and ADMINISTER permission checks in patch). Together these functions formed the attack surface for the sandbox bypass.
