CVE-2023-52202Network attack vector

Authenticated object injection via undisclosed deserialization sink

Published Jan 8, 2024 · Updated Apr 28, 2026

PHP object injection in HTML5 MP3 Player with Folder Feedburner 2.8.0 and earlier allows remote authenticated users to inject PHP objects. Public sources do not identify the vulnerable function, deserialization sink, request parameter, or wrong operation on attacker-controlled input. Exploitation requires Author privileges and a suitable POP chain, which determines whether injection leads to code execution, SQL injection, path traversal, or denial of service.
