CVE-2024-3591

The Geo Controller WordPress plugin before 8.6.5 unserializes user input via some of its AJAX actions and REST API routes, which could allow unauthenticated users to perform PHP Object Injection when a suitable gadget is present on the blog.

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.
