Summary

Oracle Helidon versions from 4.0.0 through 4.5.5 are affected through the helidon-cors component. A flaw in the CORS handling lets an unauthenticated remote attacker over HTTP change some data Helidon can access, but the attack is difficult and needs a user other than the attacker to take action. The CVSS 3.1 vector rates it as low severity with only a low integrity impact.
