Technical details
A difficult-to-exploit vulnerability in the LRA component of Helidon allows unauthenticated attackers with network access to compromise the product via HTTP. The attack has a high complexity (AC:H) but no authentication or user interaction required. Successful exploitation results in unauthorized read access to a subset of accessible data, unauthorized update/insert/delete access to some data, and the ability to cause partial denial of service; scope is changed, indicating impact beyond Helidon itself.
