CVE-2025-64227Network attack vector

Unauthenticated PHP object injection via deserialization

Published Dec 18, 2025 · Updated Dec 18, 2025

PHP object injection in BoldGrid Sprout Invoices 20.8.7 and earlier allows remote attackers to inject serialized PHP objects. The published advisory identifies deserialization of untrusted input but does not disclose the affected parameter, request path, function, or data flow. Exploitation is unauthenticated, but file deletion, sensitive-data access, or code execution requires a usable POP chain from another installed plugin or theme.
