CVE-2025-64206Network attack vector

Unauthenticated object injection via untrusted deserialization

Published Dec 18, 2025 · Updated Dec 18, 2025

PHP object injection in TieLabs Jannah 7.6.0 and earlier allows remote attackers to inject objects through untrusted serialized input. Public advisories do not identify the vulnerable handler, parameter, or deserialization call that accepts the serialized input. No known property-oriented programming chain exists in Jannah itself; code execution, file deletion, or data disclosure requires a usable chain from another installed plugin or theme.
