CVE-2023-52182Network attack vector

Authenticated PHP object injection via unsafe deserialization

Published Dec 31, 2023 · Updated Apr 28, 2026

PHP object injection in ARI Soft ARI Stream Quiz 1.3.0 and earlier allows remote authenticated users to inject PHP objects. The published advisories do not identify the affected request parameter, handler, or deserialization call that accepts the serialized input. Contributor-level access is required; the plugin has no disclosed POP chain, so file deletion, sensitive-data retrieval, or code execution also requires a usable chain from another installed plugin or theme.
