Administrator-level object injection via unserialized form_data
Published Mar 22, 2025 · Updated Apr 8, 2026
PHP object injection in WebToffee Export and Import Users and Customers 2.6.2 and earlier allows remote authenticated users to inject objects. The import and export AJAX handlers pass attacker-controlled form_data through wp_unslash and maybe_unserialize, instantiating serialized PHP objects. Administrator access is required, and impact occurs only when another installed plugin or theme supplies a usable POP chain, enabling file deletion, sensitive-data retrieval, or code execution.

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.
