CWEhttps://cwe.mitre.org/data/definitions/502.html

WordPress before 5.5.2 mishandles deserialization requests in wp-includes/Requests/Utility/FilteredIterator.php.

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.
