CVE-2026-49209: CWE-770: Allocation of Resources Without Limits or Throttling in symfony uxCVE-2026-49209 0 Symfony UX is a JavaScript ecosystem for Symfony. From 2.5.0 until 2.36.0 and 3.1.0, Symfony\UX\LiveComponent\Controller\BatchActionController::__invoke() iterates over the client-supplied actions array and issues a full HttpKernel sub-request for each entry; because the array size is never bounded, an authenticated client can submit a single _batch request containing thousands of actions and exhaust CPU, memory, and database connections on the application server. This issue is fixed in versions 2.36.0 and 3.1.0. Join the discussion | CVE Database V5 | 07/17/2026, 16:02:06 UTC Added: 07/18/2026, 11:08:40 UTC |
