CVE-2026-27379Network attack vector

Authenticated PHP object injection via unsafe deserialization

Published Mar 5, 2026 · Updated Mar 5, 2026

PHP object injection in Social Networks Auto-Poster 4.4.7 and earlier allows remote authenticated users to inject crafted objects. Vulnerable code deserializes attacker-influenced SNAP metadata, queue records, and remote OAuth responses without safely excluding PHP classes. Authenticated WordPress access is required; consequences depend on which PHP gadget methods the installation exposes.
