CVE-2023-5235

The Ovic Responsive WPBakery WordPress plugin before 1.2.9 does not limit which options can be updated via some of its AJAX actions, which may allow attackers with a subscriber+ account to update blog options, such as users_can_register and default_role. It also unserializes user input in the process, which may lead to Object Injection attacks.

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.
