CVE-2025-23932Network attack vector

Unauthenticated object injection via serialized input

Published Jan 22, 2025 · Updated May 11, 2026

PHP object injection in Marko-M Quick Count 3.00 and earlier allows remote attackers to inject objects through untrusted serialized data. Patchstack has not disclosed the affected endpoint, parameter, function, or unsafe deserialization call. The interface is network-reachable and requires no authentication; impact depends on a usable property-oriented programming chain, which can lead to code or SQL injection, path traversal, or service interruption.
