CVE-2023-1347

The Customizer Export/Import WordPress plugin before 0.9.6 unserializes user input provided via the settings, which could allow high privilege users such as admin to perform PHP Object Injection when a suitable gadget is present

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
