Unauthenticated PHP object injection
Published Jul 2, 2026 · Updated Jul 2, 2026
PHP object injection in Arraytics Booktics 1.0.21 and earlier allows remote attackers to instantiate attacker-controlled PHP objects. The CNA and Patchstack entry do not identify the request handler, input field, or PHP deserialization call that processes untrusted data. No authentication is required; the concrete downstream consequence is undisclosed and depends on a usable object gadget in installed PHP code.

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.
