Unauthenticated object injection via mexcel deserialization
Published Oct 16, 2025 · Updated Oct 16, 2025
PHP object injection in VFront 0.99.52 allows remote attackers to inject arbitrary objects through the mexcel POST parameter. The mexcel.php handler base64-decodes this user-controlled value and passes it to PHP unserialize() without validation or an allowed_classes restriction. No authentication is required; code execution, SQL injection, path traversal, or denial of service requires an exploitable class in VFront or its dependencies.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
