CVE-2024-13410Network attack vector

Unauthenticated object injection via ajax_handler deserialization

Published Mar 19, 2025 · Updated Apr 8, 2026

PHP object injection in LoftOcean CozyStay 1.7.0 and earlier and TinySalt 3.9.0 and earlier allows remote attackers to inject objects. The ajax_handler function deserializes attacker-controlled request data, allowing PHP to construct an injected object. The object has no impact by itself; a POP chain from another installed theme or plugin is required to delete files, read sensitive data, or execute code.
