Add #[Locked] attributes to prevent client-side property tampering#549
Conversation
This hardens the Modal component against Livewire hydration attacks (CVE-2025-54068). While the vulnerability was fixed in Livewire 3.6.4, adding #[Locked] to $activeComponent and $components provides defense-in-depth by preventing any client-side manipulation of these properties via the updates mechanism. The test was updated to use proper server-side methods instead of directly setting properties, which is exactly what #[Locked] prevents. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
#[Locked]attributes to$activeComponentand$componentsproperties in the Modal componentContext
While CVE-2025-54068 was fixed in Livewire 3.6.4, the
$componentsarray property made this package a convenient attack target for automated scanning. Adding#[Locked]prevents any client-side manipulation of these properties via Livewire'supdatesmechanism, eliminating this package as an attack vector even on unpatched Livewire versions.Test plan
