In lieueu of the above comment, we should update all the request and response models for execution API to forbid any extra fields. Although it makes more sense to do so for any of the PUT/POST APIs. Check under airflow/api_fastapi/execution_api/datamodels/*.py to find all the models. These models will be in sync with what is present in task_sdk/src/airflow/sdk/api/datamodels/_generated.py. Idea is to update airflow/api_fastapi/execution_api/datamodels/*.py first and make relevant changes to task_sdk/src/airflow/sdk/api/datamodels/_generated.py after.

Can I take over this ? If you assign it to me, I'll take a quick look at it.
(Do I create and link a PR first?)
