Microsoft Kiota Workspace-config poisoning: out-of-repo file write + generation-time SSRF

Summary Microsoft Kiota honors a poisoned .kiota/workspace.json — the workspace configuration that Kiota's documented team workflow has developers commit to their repository — unvalidated on kiota client generate / kiota plugin generate. A repository or pull request containing a malicious...
