CVE-2023-52225Network attack vector

Unauthenticated object injection via undisclosed deserialization

Published Jan 8, 2024 · Updated Apr 28, 2026

PHP object injection in Taggbox UGC Suite 3.1 and earlier allows remote attackers to inject objects through an unauthenticated request. The CNA record and its sole advisory reference do not identify the request parameter, PHP function, or deserialization call that accepts untrusted data. No authentication or user interaction is required; further code execution or file, database, or availability impact requires a suitable POP chain.
