CVE-2025-53586Network attack vectorHinoki check available

Authenticated object injection via undisclosed deserialization path

Published Nov 6, 2025 · Updated Nov 6, 2025

PHP object injection in NooTheme WeMusic 1.9.1 and earlier allows remote authenticated users to inject arbitrary objects over the network. Patchstack has not published the vulnerable function, input parameter, or deserialization path that accepts attacker-controlled serialized data. Low-privileged WordPress access is required; downstream effects depend on an available PHP gadget chain, and the published record does not identify one.
