Technical details
The vulnerability exists in the helidon-cors component and allows unauthenticated network-based attacks via HTTP. An attacker with network access can bypass authorization controls to gain both read access to a subset of accessible data and update/insert/delete access to some Helidon data. The scope change indicates exploitation may impact systems beyond Helidon itself.
