Sources and claim methodology

Upstream source description

SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, the `DataGrid` LiveComponent deserializes a `context` prop value using PHP's `unserialize()` after receiving it from the client. Because the prop is marked `writable: true`, an authenticated attacker can supply an arbitrary PHP serialized payload. Version 3.0.1 fixes the issue.
