  "details": "### Summary\n\nThe run replay `action` function at `apps/webapp/app/routes/resources.taskruns.$runParam.replay.ts` has no authentication or authorization check. While the `loader` (GET) in the same file properly calls `requireUser(request)` and scopes queries to the user\u0027s organizations, the `action` (POST) at line 166 does neither \u2014 allowing any authenticated user to replay task runs from any organization by knowing the run\u0027s `friendlyId`.\n\n### Details\n\n**Vulnerable file:** `apps/webapp/app/routes/resources.taskruns.$runParam.replay.ts`\n\n**The `loader` (line 28-29) \u2014 properly authenticated:**\n```typescript\nexport async function loader({ request, params }: LoaderFunctionArgs) {\n  const user = await requireUser(request);  // \u2713 Auth check\n  const userId = user.id;\n  // ... queries scoped to user\u0027s orgs\n}\n```\n\n**The `action` (line 166-193) \u2014 NO authentication:**\n```typescript\nexport const action: ActionFunction = async ({ request, params }) =\u003e {\n  const { runParam } = ParamSchema.parse(params);\n  // \u2717 NO requireUser() call\n  // \u2717 NO requireUserId() call\n  // \u2717 NO org membership check\n\n  const taskRun = await prisma.taskRun.findFirst({\n    where: {\n      friendlyId: runParam,  // Queries ANY run, no org scoping\n    },\n    include: {\n      runtimeEnvironment: { select: { slug: true } },\n      project: { include: { organization: true } },\n    },\n  });\n\n  // ... proceeds to replay the run in the victim\u0027s environment\n  const replayRunService = new ReplayTaskRunService();\n```\n\nThe Prisma query at line 177 fetches the run by `friendlyId` only \u2014 no `userId` or organization filter. The `ReplayTaskRunService` then creates a new task run in the victim\u0027s environment, executing with the victim\u0027s environment variables and secrets.\n\n**Same bug class exists in:** `apps/webapp/app/routes/resources.batches.$batchId.check-completion.ts` (line 17) \u2014 the `action` has zero authentication, allowing any user to trigger batch completion for any batch ID.\n\n### PoC\n\n**Run replay IDOR:**\n```bash\n# Any authenticated user can replay any org\u0027s task run\nPOST /resources/taskruns/run_abc123def/replay\nCookie: \u003cany-valid-session\u003e\nContent-Type: application/x-www-form-urlencoded\n\nenvironmentId=\u003cvictim-env-id\u003e\u0026failedRedirect=/\n```\n\nThe `friendlyId` values (e.g., `run_abc123def`) are short, incrementing strings that can be enumerated.\n\n**Batch completion (same bug class):**\n```bash\n# Any authenticated user can trigger batch completion for any batch\nPOST /resources/batches/\u003cbatchId\u003e/check-completion\nCookie: \u003cany-valid-session\u003e\nContent-Type: application/x-www-form-urlencoded\n\nredirectUrl=/\n```\n\n### Impact\n\n- **Cross-organization task execution:** An attacker can replay task runs belonging to other organizations, executing tasks in the victim\u0027s environment with the victim\u0027s secrets and API keys\n- **Secret exposure:** Replayed tasks run with the victim organization\u0027s environment variables, which may contain database credentials, API keys, and other secrets\n- **Resource consumption:** Attacker consumes the victim\u0027s compute quota by replaying their tasks\n- **Data integrity:** The batch completion endpoint can prematurely resume parent tasks waiting for batch results, causing data integrity issues\n- **Low attack complexity:** `friendlyId` values are short, predictable strings \u2014 enumeration is feasible",
