    "summary": "### Summary The run replay `action` function at `apps/webapp/app/routes/resources.taskruns.$runParam.replay.ts` has no authentication or authorization check. While the `loader` (GET) in the same file properly calls `requireUser(request)` and scopes queries to the user's organizations, the `action` (POST) at line 166 does neither — allowing any authenticated user to replay task runs from any organization by knowing the run's `friendlyId`. ### Details **Vulnerable file:** `apps/webapp/app/routes/resources.taskruns.$runParam.replay.ts` **The `loader` (line 28-29) — properly authenticated:** ```typescript export async function loader({ request, params }: LoaderFunctionArgs) { const user = await requireUser(request); // ✓ Auth check const userId = user.id; // ... queries scoped to user's orgs } ``` **The `action` (line 166-193) — NO authentication:** ```typescript export const action: ActionFunction = async ({ request, params }) => { const { runParam } = ParamSchema.parse(params); // ✗ NO requireUser() call // ✗ NO requireUserId() call // ✗ NO org membership check const taskRun = await prisma.taskRun.findFirst({ where: { friendlyId: runParam, // Queries ANY run, no org scoping }, include: { runtimeEnvironment: { select: { slug: true } }, project: { include: { organization: true } }, }, }); // ... proceeds to replay the run in the victim's environment const replayRunService = new ReplayTaskRunService(); ``` The Prisma query at line 177 fetches the run by `friendlyId` only — no `use",
