Authenticated PHP object injection via unsafe deserialization
Published May 9, 2024 · Updated Apr 8, 2026
PHP object injection in Metaphor Creations Ditty 3.1.38 and earlier allows remote authenticated users to inject objects when adding a Ditty. The add-Ditty workflow deserializes attacker-controlled input into a PHP object without restricting which object class can be instantiated. Contributor access is required; no usable POP chain exists in Ditty itself, so file deletion, sensitive-data retrieval, or code execution also requires a suitable chain from another installed plugin or theme.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
