  "details": "## Summary\n\nThe POST handler for `/realtime/v1/streams/:runId/:streamId` has no authentication. Any entity that knows or guesses a run friendlyId can inject arbitrary data into its realtime stream.\n\n## Vulnerability Details\n\n**File:** `apps/webapp/app/routes/realtime.v1.streams.$runId.$streamId.ts`\n\nThe `action` handler (line 17) has no auth wrapper. The code comment says: \"Plain action for backwards compatibility with older clients that don\u0027t send auth headers.\"\n\nThe run lookup at line 29 uses `where: { friendlyId: runId }` with NO environment scoping (`runtimeEnvironmentId` is not checked), so production runs are accessible.\n\nRun friendlyIds follow predictable patterns (e.g., `run_1234abcd`).\n\n## Steps to Reproduce\n\n```bash\n# No authentication required\ncurl -X POST \"http://localhost:8030/realtime/v1/streams/run_KNOWN_ID/stream_1\"   -H \"Content-Type: application/json\"   -d \u0027{\"injected\": \"data\"}\u0027\n```\n\n## Impact\n\nUnauthenticated data injection into any run realtime stream. Cross-environment access (no scoping).",
