CVE-2026-49208

Beschreibung

Symfony UX is a JavaScript ecosystem for Symfony. From 2.8.0 until 2.36.0 and 3.1.0, when a #[LiveProp] is typed as DateTimeInterface and no explicit format is configured, Symfony\UX\LiveComponent\LiveComponentHydrator::hydrateObjectValue() falls back to new $className($value), allowing client-supplied relative strings such as now, tomorrow, or +10 years to move a writable, format-less date prop past time-based business logic checks. This issue is fixed in versions 2.36.0 and 3.1.0.
