medium Tenable Self-Hosted Container Security Plugin ID 443649

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-49208)

Solution

Update the symfony/ux-live-component library and its related packages to version 2.36.0 or later.
