CVE-2026-61686Network attack vector

Object injection via writable serialized context

Published Sep 4, 2026 · Updated Sep 4, 2026

PHP object injection in SolidInvoice before 3.0.1 allows remote authenticated users to submit serialized payloads to DataGrid. DataGrid.php marks the context LiveProp writable and passes its client-supplied value directly to hydrateContext(), which invokes PHP unserialize(). Any authenticated user can reach the update endpoint, but code execution or file access requires a compatible gadget chain, and no known gadget is reported.
