description

a2a-java releases before 1.3.0.Final may allow task records to be read without verifying that the requester owns them. In multi-caller deployments using the default store or handlers without effective task authorization, an unauthenticated requester who obtains a task identifier may access its status, context, history, and artifacts.

mitigation

Upgrade a2a-java to version 1.3.0.Final or later. Until upgraded, configure a TaskAuthorizationProvider, ensure requests pass through the authorization decorator, and require authentication on exposed transport endpoints.

fixed in 1.3.0.Final
