Does this matter?
Lower severity and a low EPSS score (1.55%). Track it; it rarely justifies an emergency change on its own.
Description
In Apache Ozone before 1.2.0, Ozone Datanode doesn't check the access mode parameter of the block token. Authenticated users with valid READ block token can do any write operation on the same block.
