Technical details
The vulnerability is a PHP Object Injection (CWE-502: Deserialization of Untrusted Data) in the DataGrid LiveComponent's context prop handler. The `hydrateContext()` method calls `unserialize()` on client-supplied input after receiving it via a writable LiveComponent prop, even though it restricts instantiation to the `Ulid` class. An authenticated attacker can craft a serialized PHP payload and submit it through a LiveComponent update request to trigger deserialization. Depending on gadget chains present in the application's dependency graph, this could lead to arbitrary code execution or unauthorized file system access. The fix, released in version 3.0.1, replaces the serialize/unserialize pair with JSON encoding.
