# Oracle PeopleSoft PeopleTools: Fluid Core flaw allows limited data read and write

A flaw in the Fluid Core component of Oracle PeopleSoft PeopleTools, versions 8.61 to 8.63, lets a low-privileged user reach data over HTTP after another person interacts with a crafted request. An attacker can read a subset of accessible data and update, insert or delete some records.

_Summary, check and fix written by a model from the sources; labelled as such._
