GHSA-4m4j-hmqq-3gxm | symfony/ux-live-component: CSRF Protection Bypass — Accept Header is CORS-Safelisted |
Fri, 17 Jul 2026 16:30:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | Symfony UX is a JavaScript ecosystem for Symfony. From 2.22.0 until 2.36.0 and 3.1.0, Symfony\UX\LiveComponent\EventListener\LiveComponentSubscriber::isLiveComponentRequest() gates #[LiveAction] invocations on Accept: application/vnd.live-component+html, but the Accept header is CORS-safelisted and cross-origin fetch() can set it without preflight, allowing forged cross-origin #[LiveAction] requests against a victim session when applications use SameSite=None, credentials: 'include', a permissive cookie policy, or a same-origin pivot. This issue is fixed in versions 2.36.0 and 3.1.0. | |
