Submit #925152: a2a-project a2a-java v1.2.0.Final CWE-862info

Titlea2a-project a2a-java v1.2.0.Final CWE-862
DescriptiononListTasks in AuthorizationRequestHandlerDecorator delegated directly to the wrapped handler without any authorization check, unlike every other handler method which calls an enforce* check first. With a TaskAuthorizationProvider configured, a caller could invoke listTasks and bypass the authorization model entirely — only per-task filtering in the TaskStore (which custom store implementations may skip) stood between the caller and other users' tasks.
