Go to dashboardOracle's Helidon framework has a flaw in its IDCS mapper security provider. A low-privileged user with logon access to the host where Helidon runs can reach data Helidon handles, with a scope change that can affect other products.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-23 21:57 UTC. All times on this page are UTC.
Teams running Helidon 3.0.0 through 3.2.21 or 4.0.0 through 4.5.5 that use the IDCS mapper security provider. The attacker needs a local login on the machine or container where Helidon executes, so exposure is lowest for services with no shared shell access. Teams on other Helidon versions or without the IDCS mapper module can skip it.
