CVE-2025-26999

Deserialization of Untrusted Data vulnerability in Metagauss ProfileGrid allows Object Injection. This issue affects ProfileGrid : from n/a through 5.9.4.3.

Weakness

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

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.
