Unauthenticated object injection via unsafe deserialization

Published Jun 17, 2026 · Updated Jun 17, 2026

PHP object injection in Edge Themes Reina 2.1 and earlier allows remote attackers to submit malicious serialized objects without authentication. Patchstack and the CNA record do not disclose the affected request handler, parameter, or unsafe deserialization operation. A reachable WordPress site and a suitable property-oriented programming chain are required; reported outcomes include code injection, SQL injection, path traversal, and unspecified denial of service.
